Abstract:
1. An analog front end device, comprising: a reference voltage generator for generating a reference voltage; a clock generator for generating a clock signal; a clamper for adjusting a DC level of an analog signal to generate a second analog signal; a buffer for receiving the reference voltage and buffering the second analog signal to generate a buffering signal; an analog to digital converter receiving the reference voltage and the clock signal for converting the buffering signal into a digital signal; and a temperature compensation circuit for providing a compensating signal to at least one of the reference voltage generator and the clock generator; wherein the clock generator adjusts the clock signal responsive to the compensating signal; and wherein the reference voltage generator adjusts the reference voltage to compensate at least one of the buffer and the analog to digital converter when the compensating signal is provided to the reference voltage generator.
