摘要
In this paper the design of a CMOS transconductance amplifier, able to drive couples of quantum well diodes, is discussed. The circuit is proposed in two different implementations whose selection depends on the availability of a single well or a twin well technology. Both the implementations are characterized by an intrinsic control of input stages' threshold and gain-linearity (THD < 1% for twin well technologies), as well as by a 3 dB bandwidth > 100 MHz.
