Abstract
An analog-to-digital converter is disclosed comprising a resonant oscillator comprising an input operable to receive an analog input signal and an output operable to output an oscillating signal. A DC offset detector detects a DC offset in the oscillating signal caused by the analog input signal, wherein the DC offset is converted into a digital output signal representing the analog input signal.
Claims22
An analog-to-digital converter comprising:
- a resonant oscillator comprising an input operable to receive an analog input signal and an output operable to output an oscillating signal;
- and
