Abstract :
A very simple power supply rejection ratio (PSRR) enhancement technique is presented. It is suitable, among others, for low voltage power low power (LVLP) DC circuits such as biasing circuits. It is shown that a high insensitivity to AC noise in supply rails can be achieved with an almost zero contribution to the total internal noise. This is achieved at the expense of very small additional circuitry and no additional power dissipation or supply requirements. Simulation and experimental verification of these characteristics is provided.
