“…The idea is simply to route the thermal-noise current of the input stage to two nodes in the circuit such that their contributions are in phase, then taking the output as the difference between the voltages of these two nodes. A similar idea can be found in Custódio et al 45 In Wu and Ho, 46 C.-Y. Wu et al have propsed an inverter-based folded cascode amplifier to be used in signal acquisition systems.…”

The CMOS inverter can be used as an amplifier if properly biased in the transition region of its voltage-transfer characteristics (VTC). In this paper, the design of this amplifier is investigated with its merits and demerits illustrated and with the various trade-offs involved in its design discussed. Specifically, the following performance metrics are discussed quantitatively: gain, area, linearity, maximum allowable swing, bandwidth, stability, noise factor, impedance matching, and slew rate. Also, the effect of process, voltage, and temperature (PVT) variations are investigated. The optimum number of stages corresponding to the minimum area required for achieving a certain voltage gain is determined. The results obtained from the quantitative analysis and the simulation are discussed.

“…A similar idea can be found in Custódio et al 45 In Wu and Ho, 46 C.-Y. In the latter TIA, a noise-canceling circuitry consisting of a CMOS inverter and a current mirror was proposed to cancel the thermal noise of the MOS transistors of the CMOS inverter at the input stage.…”
