Abstract: A track and hold circuit that includes a switch device and a capacitive hold device. The track and hold circuit includes a track-voltage generating device adapted to generate a control voltage based on a signal on an input terminal of the switch device and supply the control voltage to the switch device during track phases of the track and hold circuit. The control voltage provides a channel charge, which is the same for each track phase, in the switch device.

Abstract: A track and hold circuit (1) comprising a switch device (10) and a capacitive hold device (20). The track and hold circuit (1) comprises a track-voltage generating device (30) adapted to generate a control voltage based on a signal on an input terminal of the switch device (10) and supply the control voltage to the switch device (10) during track phases of the track and hold circuit (1). The control voltage provides a channel charge, which is the same for each track phase, in the switch device (10).

Abstract: A method for operating a time-interleaved analog-to-digital converter for converting an analog input to a digital output using a time-interleaved analog-to-digital converter, wherein the time-interleaved analog-to-digital converter comprises an array of M sub ADCs (ADC1, ADC2, . . . , ADCM), where M is an even integer, and each row of the array comprises one of the M sub ADCs. The method comprises the step of, for every sampling instant n, where n is an integer in a sequence of integers, converting the analog input by means of the sub ADC in row k(n) of the array, wherein 1?k(n)?M. A value between 1 and M is assigned to k(n) for the first sample instant, and k(n+1) is selected such that a) k(n+1)>M/2 if k(n)?M/2, otherwise k(n+1)?M/2; b) M/2?1?|k(n+1)?k(n)|?M/2+1; and c) k(n+1)=k(m+1) if and only if n?m is an integer multiple of M. A time interleaved analog-to-digital converter operating in accordance with the method is also disclosed.
