ABSTRACT:
A transconductance amplifier 12 includes a differential input connected to a current amplification network and a source follower output connected to the current amplification network. The CMOS topology coupled with the source follower type output provide an extremely low current, low output impedance transconductance amplifier. The source follower output includes low threshold voltage transistors that also provide an extremely large output voltage swing.
