CIRCUIT AND METHOD FOR INCREASING OPERATIONAL SPEED OF AMPLIFICATION CIRCUIT

摘要

A circuit and a method for increasing the operational speed of an amplification circuit are provided to perform rapid switching and operate in a high frequency by reducing the settling time of an output voltage. A circuit for increasing the operational speed of an amplification circuit(300) includes a first capacitor(CP), a second capacitor(CN), and a switch array. The switch array serially connects the first capacitor and the second capacitor between a first node(N1) which supplies a first voltage level and a second node(N2) which supplies a second voltage level in response to a first control signal(FR_ON), or separates the first capacitor and the second capacitor from the first node and the second node and cross-connects the first capacitor and the second capacitor. The switch array adjusts the capacitance of the first and second capacitors in response to a second control signal.
