Abstract
A loop compensation circuit includes a differential difference amplifier having a first transconductance stage with a first input terminal and a second input terminal. The first input terminal is coupled to a voltage reference and the second input terminal is coupled to a feedback node. The amplifier also includes a second transconductance stage having a third input terminal and a fourth input terminal. The third input terminal is coupled to a virtually specified fixed voltage and the fourth input terminal is coupled to a fixed specified voltage. The loop compensation circuit also includes a feedback impedance coupled between an output of the differential difference amplifier and the third input terminal and a second impedance between the third input terminal and the fixed specified voltage.
