Signal sampling circuit
Louwsma, Simon Minze and Vertregt, Maarten (2010) Signal sampling circuit. Patent.
|Abstract:||A sampling circuit for sampling a signal is disclosed. The sampling circuit comprises a plurality of sampling channels adapted to sample the signal in time-multiplexed fashion, each sampling channel comprising a respective track-and-hold circuit connected to a respective analogue to digital converter via a respective output switch. The output switch of each channel opens for a tracking time period when the track-and-hold circuit is in a tracking mode for sampling the signal, and closes for a holding time period when the track-and-hold circuit is in a holding mode for outputting the sampled signal. The holding time period comprises a settling time period that is at least as long as the tracking time period. The settling time period is used by the track-and-hold circuit to charge an input capacitance of the analogue to digital converter to a voltage according to the sampled signal.
