Mathematical Circuit Root Simplification Using an Ensemble Heuristic–Metaheuristic Algorithm

Mathematics, 2023
Symbolic pole/zero analysis is a crucial step in designing an analog operational amplifier. Generally, a simplified symbolic analysis of analog circuits suffers from NP-hardness, i.e., an exponential growth of the number of symbolic terms of the transfer

CMOS OTA-C high-frequency sinusoidal oscillators [PDF]

, 1991
Several topology families are given to implement practical CMOS sinusoidal oscillators by using operational transconductance amplifier-capacitor (OTA-C) techniques. Design techniques are proposed taking into account the CMOS OTA's dominant nonidealities.
