Current Follower With Zero Input Impedance

View page
US Patent:
56148674, Mar 25, 1997
Filed:
Jun 28, 1994
Appl. No.:
8/266567
Inventors:
Gerald M. Cotreau - Melbourne FL
Assignee:
Harris Corp. - Melbourne FL
International Classification:
H03F 304
US Classification:
330288
Abstract:
A semiconductor current follower and method using a copy of the input current from a current mirror to insure that the input impedance remains a virtual ground for both unidirectional and bidirectional signals.

High Speed Low Input Current Voltage Follower Stage

View page
US Patent:
48916048, Jan 2, 1990
Filed:
Dec 27, 1988
Appl. No.:
7/289747
Inventors:
Gerald M. Cotreau - Melbourne FL
Assignee:
Harris Corporation - Melbourne FL
International Classification:
H03F 345
US Classification:
330252
Abstract:
A voltage follower input stage having a correction or bootstrap circuit to effectively remove the parasitic capacitance by bootstrapping the capacitance so that both sides of the parasitic capacitance follows voltage level changes.

Front End Stage Of An Operational Amplifier

View page
US Patent:
46367438, Jan 13, 1987
Filed:
Oct 1, 1985
Appl. No.:
6/782690
Inventors:
Gerald M. Cotreau - Melbourne FL
Assignee:
Harris Corporation - Melbourne FL
International Classification:
H03F 368
US Classification:
330295
Abstract:
The front end of an operational amplifier having an improved slew rate and high gain current output capabilities. The amplifier includes a slew enhancement or large signal stage connected in parallel to a normal front end or small signal stage. The small signal stage supplies a transconductance output which is approximately linearly related to the input until its slew rate limit. The slew enhancement stage is designed to provide slew current when the small signal stage reaches its slew rate limit, thereby providing an increased output current response to an increasing differential input voltage beyond the slew rate of the small signal stage.

Filter With Reduced Element Ratings And Method

View page
US Patent:
55721621, Nov 5, 1996
Filed:
Jan 30, 1995
Appl. No.:
8/380412
Inventors:
Gerald M. Cotreau - Melbourne FL
Assignee:
Harris Corporation - Melbourne FL
International Classification:
G06F 7556
US Classification:
327552
Abstract:
An electronic filter for passing predetermined frequencies includes resistive and capacitive components that need not be rated to handle the input voltage. An input signal is converted to a second signal that is proportional to the logarithm of the input signal (and therefore of much smaller magnitude than the input signal), and then low, high, bandpass filtered with an RC filter. The filtered signal is reconverted to an output signal that is proportional to the inverse logarithm of the filtered signal. The filter may be embedded in a current mirror that may be used in telephone system subscriber line interface circuit.

Front End Stage Of An Operational Amplifier

View page
US Patent:
47836377, Nov 8, 1988
Filed:
Oct 7, 1986
Appl. No.:
6/917441
Inventors:
Gerald M. Cotreau - Melbourne FL
Assignee:
Harris Corporation - Melbourne FL
International Classification:
H03F 345
H03F 368
US Classification:
330295
Abstract:
The front end of an operational amplifier having an improved slew rate and high gain current output capabilities. The amplifier includes a slew enhancement or large signal stage connected in parallel to a normal front end or small signal stage. The small signal stage supplies a transconductance output which is approximately linearly related to the input until its slew rate limit. The slew enhancement stage is designed to provide slew current when the small signal stage reaches a selected threshold such as its slew rate limit, thereby providing an increased output current response to an increasing differential input voltage beyond the slew rate of the small signal stage. The large signal stage can be optimized to provide a greater input linear dynamic range, faster slew rate and improved efficiency.

High Accuracy, High Impedance Differential To Single-Ended Current Converter

View page
US Patent:
48795232, Nov 7, 1989
Filed:
Nov 18, 1988
Appl. No.:
7/272908
Inventors:
Gerald M. Cotreau - Melbourne FL
Assignee:
Harris Corporation - Melbourne FL
International Classification:
H03F 304
US Classification:
330288
Abstract:
A correction circuit is provided to improve current accuracy by sensing the error current of a first variable current source and substracting it from the output of a second variable current source. It also increases output impedence by sensing incremental output current and cancelling its effect.

Circuit For Increasing Voltage Gain

View page
US Patent:
45609489, Dec 24, 1985
Filed:
Jul 12, 1984
Appl. No.:
6/630280
Inventors:
John S. Prentice - Palm Bay FL
Gerald M. Cotreau - Melbourne FL
Assignee:
Harris Corporation - Melbourne FL
International Classification:
H03G 330
H03F 134
US Classification:
330282
Abstract:
An operational amplifier having an input stage, a voltage gain stage, a current gain or buffer stage and a feedback connected between the output of the buffer stage for supplying to the voltage gain stage a current which varies in proportion to the voltage gain stage output to increase the output impedance of the voltage gain stage.

Current Mode Ring Trip Detector

View page
US Patent:
56712723, Sep 23, 1997
Filed:
Jan 30, 1995
Appl. No.:
8/380409
Inventors:
Gerald Michael Cotreau - Melbourne FL
Assignee:
Harris Corporation - Melbourne FL
International Classification:
H04M 302
US Classification:
379382
Abstract:
A circuit and method for sensing in current mode when a telephone has been answered in a telephone system in which an answer is indicated when a dc component of a signal across a resistor exceeds a predetermined reference current. Currents sensed at the terminals of the resistor are combined to provide a third current that includes the dc component, without attenuation of the dc component. A filter separates the dc component from the third current so that the dc component can be compared to the reference current.
