A differential variable gain transconductance amplifier suitable for but not limited to applications requiring operation with a power supply of less than 1. 0V. The circuit is suitable for fabrication by integrated circuit technology and is composed of three major blocks: an input stage, a current summing gain control stage, and an output stage. The differential input stage is comprised of two identical voltage-to-current converters, with one used as the positive input and the other as the negative input. The current summing stage uses the principal of summation of opposite but equal currents canceling to produce attenuated gain. The output stage converts current into voltage and produces a single ended output.

Abstract:
A precision motor speed control system employing a phase locked loop in which the inertial mass of the motor, its tachometer and motor driven devices, such as fly wheels, tape transports, etc. , perform the functions of the usual low pass filter and voltage control oscillator.

Abstract:
A transistor interface circuit for switching analog differential pairs in response to a flip-flop or combinational logic, both output signals of which remain either high or low during switching transitions. This circuitry prevents the differential pair from momentarily saturating or shutting off during the switching transition.
