If the PMOS and NMOS transistors are sized so that g m1 = g mb2, the V sub term vanishes and I x = V x(g m1 + g mb1). In this case, the active load impedance Z LOAD = 1/ (g m1 + g mb1 ) and doesn ...

By using PMOS transistors as the differential pair, the amplifier is optimized for handling negative or low-voltage input signals, while the NMOS current mirror acts as an active load to enhance gain ...

This circuit is a common-source amplifier made using both a PMOS (M2) and NMOS (M1) transistor. The main components are: VDD (Supply Voltage): 1.8V Input Signals (V1 and V2): V1: 0.48V peak sine wave, ...

Design and chip fabrication results for complementary RF circuit topologies that utilize the complementary RF characteristics of both NMOS and PMOS field-effect-transistor devices combined in parallel ...

In this paper we present an ultra-low voltage gate-input operational transconductance amplifier using pMOS input devices and nMOS load devices with local common-mode feedback. This topology has a good ...
