Abstract

A low noise linear amplifier and a microwave voltage controlled oscillator constructed from such amplifier. Each amplifier within the VCO utilizes a ratioed transistor configuration to generate a linear output over a wide range of inputs. Output current from the amplifier is split into a main output current and components of in-phase and 180· out-of-phase current. A
logarithmic tuning control combines the components of in-phase and 180· out-of-phase currents in inverse ratio to provide a constant d.c. feedback current.
