Popis:	This paper presents design considerations on CMOS limiting amplifiers to be used as basic building blocks for power-efficient logarithmic amplifiers. The impact of mismatches and device-level properties on sensitivity and gain-bandwidth product is discussed. To this end, a comparison of several types of low-voltage gain cell topologies is presented. Based on statistical (Monte Carlo) results, a high-sensitivity eight-stage limiting amplifier tolerant of process spreads and devices mismatches was designed in [email protected] CMOS technology to operate over dc to 20MHz bandwidth and experimentally evaluated. The proposed limiting amplifier draws [email protected] from a 2-V supply and achieves a voltage gain of 72dB.
