An amplifier includes a differential input with a positive and a negative input and an analog integrator with a differential integrator input and a differential integrator output. The analog integrator further includes an operational amplifier with a positive operational amplifier input, a negative operational amplifier input, a positive operational amplifier output and a negative operational amplifier output. The differential integrator input is coupled to the differential input. A ternary pulse width modulator includes two modulator inputs coupled to the differential integrator output and two modulator outputs. A first feedback path is coupled between a first of the two modulator outputs and the positive operational amplifier input and a second feedback path is coupled between a second of the two modulator outputs and the negative operational amplifier input. A first divert capacitor is coupled between the positive operational amplifier input and a constant voltage reference. A second divert capacitor is coupled between the negative operational amplifier input and the constant voltage reference.
