Abstract:
1. An electronic device for analog-to-digital conversion comprising: a sigma-delta modulator (SDMOD); a digital filter (FIL) for digital post processing of the output signal of the sigma-delta modulator (SDMOD), said digital filter including registers storing content representing the internal state relating to a specific input signal; a multiplexer (MUX) for switching the input (INSD) of the sigma-delta modulator (SDMOD) between a first input signal (IN a memory (MEM) adapted to hold the register content of said digital filter (FIL) relating to said first input signal while said second input signal (IN a controller (CNTL) operable to retrieve the register contents relating to said first input signal from said memory (MEM) when said digital filter (FIL) resumes processing of said first input signal (IN
