Device for a voltage regulator with improved power supply rejection ratio (psrr- power supply rejection ratio) with reduced parasitic capacitance bias signal lines

摘要

A system with an improved power supply rejection ratio,the system comprising:a regulated power supply;a functional block with a gate element and a switching element, wherein the gate element is connected with the switching element and the switching element, the electrically gate element is connected with the controlled power supply;a bias source to the provision of bias current; anda bias circuit, which the bias source and the functional block, in order to electrically couples the bias current to the function block, wherein the switching element is provided, to make it possible for the bias current flows into the function block when the switching element is switched on by the gate element.
