Abstract
A transconductance amplifier for use in a low noise, microwave voltage controlled oscillator. The transconductance amplifier incorporates a linear amplifier having ratioed transistors to provide linearized gain. A tuning arrangement combines in-phase and out of phase currents in an inverse ratio to provide a constant D.C. current sum. The tuning circuit has been arranged to operate without a cascode stage such that the power supply voltage requirement is reduced from 5.0 volts to 3.3 volts.
