Amplififers With Field-Effect Devices TRIZ Cases
- LDO PSR Enhancer Using Negative Capacitance Cancellation
Negative capacitance and adaptive biasing help an LDO reject supply noise across process corners while avoiding unnecessary power draw.
- Pseudo Class-AB Output Circuit for Linearity and Low Headroom
A PMOS-NMOS output stage uses parallel gate capacitor and impedance biasing to keep linearity and power efficiency under low headroom.
