Classification: CPC H  G | IPC G  H

Claim 9:
10. The circuit of claim 5, wherein:
the one or more capacitors connected between the third node and the fourth node comprise a switchable first capacitor arranged to controllably couple and decouple from between the fourth node and the third node and a second capacitor, wherein during the third operating phase the switchable first capacitor is decoupled and the second capacitor operates to adjust a common mode voltage at the fourth node, and during the fourth operating phase both the switchable first capacitor and the second capacitor provide a first positive feedback gain, and
the one or more capacitors connected between the second node and the fifth node comprise a switchable third capacitor arranged to controllably couple and decouple from between the fifth node and the second node and a fourth capacitor, wherein during the third operating phase the switchable third capacitor is decoupled and the fourth capacitor operates to adjust the common mode voltage at the fifth node, and during the fourth operating phase both the switchable third capacitor and the fourth capacitor provide a second positive feedback gain.
