Abstract
A receiver may include a time-interleaved charge sampler comprising a charge sampler switch in series with a charge sampler capacitor. The receiver may also include a current buffer configured to drive the time-interleaved charge sampler.
Claims18
A receiver comprising:
- a time-interleaved charge sampler comprising a charge sampler switch in series with a charge sampler capacitor;
- a current buffer configured to drive the time-interleaved charge sampler;
- and
- a dump switch coupled to the current buffer and in parallel with the charge sampler capacitor.
1 more element
A method of using a time-interleaved charge sampler, comprising:
- sampling a current-mode input signal at a charge sampler switch to integrate an analog value of the current-mode input signal in a charge sampler capacitor;
- quantizing the analog value integrated in the charge sampler capacitor;
- and
- controlling the charge sampler switch and a dump switch to attenuate the current-mode input signal at an aliasing frequency.

A receiver comprising:
- a time-interleaved charge sampler comprising a charge sampler switch in series with a charge sampler capacitor;
- means for driving the time-interleaved charge sampler;
- and
- a dump switch coupled to the means for driving and in parallel with the charge sampler capacitor.
