A first and second input is supplied to an integrator circuit and a first capacitor is coupled between a first output of the integrator circuit and the first input and a second capacitor is coupled between a second output and the second input of the integrator circuit during a first time period of the pulse width modulated signal. A third capacitor is coupled between a first output of the integrator circuit and the first input and a fourth capacitor is coupled between a second output of the integrator circuit and the second input during a successive second time period of the pulse width modulated signal.

Abstract: A circuit is used in the output stage of an operational amplifier which allows a rail to rail swing of the output voltage while consuming low quiescent power. The circuit includes first and second control elements each having a controllable path and a control node. The circuit further includes a third control element having a controllable path connected between the control nodes of the first and second control elements via a resistive path. A voltage indicative of an input signal is applied to a node of the resistive path. Current flow through the controllable paths of the first and second control elements changes in response to changes in the voltage at the node. More specifically, current flow through the controllable path of the second control element changes in dependance on the current flow through the controllable path of the third control element. Additionally, as one of the first and second control elements is turned on, the other control element is held off.
