Abstract :
A simple linear programmable BiCMOS transconductor is introduced. It mainly consists of an inverting amplifier with an emitter degeneration. The driver transistor is bipolar and the equivalent resistor is an MOS transistor operating in the linear region. This transconductor can be employed in high frequency continuous-time current-mode filters. Simulated and experimental results of filters show the validity of the proposed transconductor.
