Horizontal Deflection Circuit Including Protection For Output Transistor

View page
US Patent:
42412960, Dec 23, 1980
Filed:
May 29, 1979
Appl. No.:
6/043280
Inventors:
Archie M. Barter - Beaverton OR
Assignee:
Tektronix, Inc. - Beaverton OR
International Classification:
H01J 2970
US Classification:
315397
Abstract:
A circuit for driving and protecting the horizontal output transistor of a resonant raster scan display is disclosed. The driving circuitry described provides a circuit for separately establishing the currents required to turn a horizontal output transistor on and off. This transistor is turned on by a forward base current determined by beta requirements and turned off by a reverse base current equal to one half of the forward collector current. Protection against several common circuit failures is also incorporated in the circuit.

Low Power Ccd Driver With Symmetrical Output Drive Signal

View page
US Patent:
55006159, Mar 19, 1996
Filed:
Mar 28, 1995
Appl. No.:
8/412352
Inventors:
Archie M. Barter - Beaverton OR
Assignee:
Tektronix, Inc. - Wilsonville OR
International Classification:
H03K 1714
US Classification:
327111
Abstract:
A CCD gate driver circuit provides an output drive signal in response to an input clock signal. The output drive signal is symmetrical, uses a minimum amount of power at high frequencies, and compensates for cross-coupling between CCD gates. An input circuit receives the input clock signal and converts it to current pulses on the transitions of the input clock signal. The current pulses are applied to a common input of a pair of complementary input transistors to switch conduction of the transistors. The control inputs of the input transistors are coupled to a reference voltage level. The outputs of the input transistors are coupled to respective current mirrors. The outputs of the current mirrors are in turn coupled to respective inputs of a pair of complementary output transistors that have a common output. A pair of voltage rails that define the voltage swing of the output drive signal are coupled to the respective control inputs of the output transistors. Provision is made to compensate for capacitive intercoupling between the CCD gates being driven, and to provide a trickle current between clock signal transitions to maintain the output at the respective voltage rail.

Crt Video Drive Circuit With Beam Current Stabilization

View page
US Patent:
44424582, Apr 10, 1984
Filed:
Mar 29, 1982
Appl. No.:
6/363342
Inventors:
Archie M. Barter - Beaverton OR
Assignee:
Tektronix, Inc. - Beaverton OR
International Classification:
H04N 568
H04N 518
US Classification:
358243
Abstract:
The drive circuit of the present invention is characterized by a second amplifier for amplifying the video signal which controls the voltage at the control grid G. sub. 1 of the cathode-ray tube. This second amplifier has a wider bandwidth than the similar amplifiers of the prior art. It therefore generates a signal having a lower dynamic range than the dynamic ranges of the output signals associated with the similar amplifiers of the prior art. To compensate for the lower dynamic range of the output signal generated by the second amplifier, the drive circuit of the present invention measures the current in the cathode of the cathode-ray tube, converts this measured current into a voltage, stores the voltage in a capacitance, and amplifies the stored voltage in a fourth amplifier. The fourth amplifier generates a signal having a wider dynamic range than the dynamic range of second amplifier. The output of the fourth amplifier is combined with the output of the second amplifier.

Lateral Convergence Correction System

View page
US Patent:
44319495, Feb 14, 1984
Filed:
Mar 31, 1982
Appl. No.:
6/364077
Inventors:
Clayton C. Wahlquist - West Valley City UT
Archie M. Barter - Beaverton OR
Assignee:
Tektronix, Inc. - Beaverton OR
International Classification:
H01J 2970
H01J 2976
US Classification:
315368
Abstract:
An improved lateral convergence deflection system for a delta-gun shadow mask color CRT includes first, second and third lateral convergence coils mounted on the CRT neck radially outward from the paths of the electron beams from the three guns. The coils are connected in series electrically, and are of suitable strength and orientation to provide a substantially unidirectional, vertical field in the path of one (e. g. , the blue) beam, and field nulls in the paths of the other two (e. g. the red and green beams). By varying the current passed through the coil by a convergence drive amplifier, the blue beam may be shifted laterally without producing any substantial movement of the other two beams.

Current And Voltage Protection For A Power Supply Circuit

View page
US Patent:
44647093, Aug 7, 1984
Filed:
Apr 6, 1982
Appl. No.:
6/366013
Inventors:
Archie M. Barter - Beaverton OR
Assignee:
Tektronix, Inc. - Beaverton OR
International Classification:
H02H 7122
US Classification:
363 16
Abstract:
A power supply circuit comprises a main transformer having a primary winding and a secondary winding, a series resonance circuit coupled to the primary winding of the main transformer, and a switching circuit for alternately supplying DC power to the series resonance circuit and discharging the energy stored therein. A current protection circuit controls the switching circuit in dependence upon the current in the switching circuit and a voltage protection circuit controls the switching circuit in dependence upon the voltage of the secondary winding of the main transformer.
