Abstract
An improved voltage controlled amplifier employing an operational transconductance amplifier which is temperature independent and offering an improved dynamic range for the input signal is disclosed. An operational amplifier configured in the inverting mode is used as an input device having a first operational transconductance amplifier in the feedback path as a gain control element. The output of the operational amplifier provides a control voltage to effectively drive a second operational transconductance amplifier.
