Title: Control circuit for automatic control feed forward non-linear distortion compensating amplifier
Inventor: SAKAMOTO HIROTOKU
IPC: H03G5/16
Filed: 1992-02-27
Abstract: PURPOSE:To realize temperature compensation with simple circuit configuration and to facilitate the control of an FF amplifier. CONSTITUTION:The operations of variable attenuators 14 and 24 and variable phase shifters 16 and 26 provided in a distortion detection loop 10 and a distortion removal loop 22 are controlled by an adder circuit 42. The adder circuit 42 adds a temperature compensating voltage or an adjusting voltage from a heat sensitive element to a control signal from an automatic control circuit 44 and defines that voltage as a control voltage. Since the temperature compensation is realized by the adder circuit 42, the most satisfactory control state is realized even in a free run state. It is not necessary to separately provide any variable attenuator or variable phase shifter for adjusting the FF amplifier. Further, since it is not necessary to separately adjust a main amplifier 18 or an auxiliary amplifier 28, the adjustment is facilitated.

Title: Voltage comparator
Inventor: OGASAWARA HIROSHI
IPC: H03K5/08
Filed: 1995-03-03
Abstract: PURPOSE: To improve the velocity and the accuracy of comparing and judging while saving the number of elements to use. CONSTITUTION: In order to comparing analog input voltage Ain with plural comaparing reference voltage, preamplifiers PA0 to PA(n-1) are provided for each comparing reference voltage. Those are successively operated to amplify voltage equivalent to the difference between analog input voltage and corresponding one of the plural reference voltage. On the other hand, in accordance with successive operation like this, a multiplexer MX selects the output of these preamplifier and outputs it to a trailing amplifier FA. As the trailing amplifier FA is shared, the number of the elements are reduced. In addition, the multiplexer prevents the deterioration of the judging velocity caused by the mutual interference between preamplifiers.
