Abstract
A current correction circuit () has an input () and includes: a first controllable current source () having an input connected to the circuit input for drawing a first current (I) from the circuit input; a differentiator () having an input coupled to the circuit input and having an output coupled to the first current source; and/or a second controllable current source () having an input connected to the circuit input for drawing a second current (I) from the circuit input; a voltage comparator () having a first input coupled to the circuit input (), having a second input coupled to receive a reference signal (Vref), and having an output coupled to the second current source. The circuit is responsive to voltage changes by drawing first current pulses () from the circuit input, and/or to low voltages by drawing second current pulses () from the circuit input.
