A Two-Stage CMOS Amplifier with High Degree of Stability for All Capacitive Loads

A Two-Stage CMOS Amplifier with High Degree of Stability for All Capacitive Loads” is to design and demonstrate a two-stage CMOS amplifier that remains unconditionally stable for any value of capacitive load. The work aims to overcome the traditional stability limitations of conventional two-stage amplifiers by introducing a compensation technique that generates a left-half-plane zero, which effectively tracks or cancels the output pole under varying load conditions. By doing so, the amplifier achieves stable operation similar to a single-pole system across process, voltage, temperature, and load variations, making it highly suitable for robust VLSI and analog integrated circuit applications.
