Abstract
An integrated circuit comprises a threshold generation circuitry for generating at least one differential voltage signal. The threshold generation circuitry comprises at least one common mode current generation circuit arranged to generate at least one common mode current signal, whereby said at least one common mode current signal is combined with at least one input current signal to produce a combined current signal comprising a combined signal common mode component. Conversion circuitry is arranged to receive the combined current signal and convert the combined current signal into the at least one differential voltage signal for use within the comparator circuit. The threshold generation circuitry further comprises feedback circuitry arranged to receive an indication of the combined signal common mode component, compare the received indication to a reference value, and regulate the at least one common mode current signal based at least partly on the comparison results.
