发明名称 Phase lead compensation circuit for an integrated switching regulator
摘要 The invention allows a phase lead compensation circuit to be integrated on the same chip as a switching regulator. The invention provides additional phase to the loop gain of the monolithic switching regulator. The additional phase is required near the unity gain frequency of the loop gain and is not continued indefinitely. The desired phase lead compensation function can be accomplished through the use of a transconductance amplifier driving a frequency-dependent load. The transconductance amplifier converts a differential input voltage signal into a single-ended output current. This output current flows through the frequency-dependent load.
