Abstract
The invention relates to an electronic circuit and a method capable of providing feedback in the electronic circuit, such that the effect of leakage currents in the circuit are minimised. The method includes the steps of storing an analogue input signal using an analogue storage device, converting the stored analogue input signal into a digital signal and storing the digital signal, converting the stored digital signal into an analogue feedback signal, and providing feedback in the electronic circuit using the analogue feedback signal.
