Abstract
A mixed-signal unit including a sampler circuit and a tracking filter. The sampler circuit converts a code into a reference signal. In response to comparing an input signal to the reference signal, the sampler circuit produces a bitstream. Upon receiving the bitstream from the sampler circuit, the tracking filter updates the code using information contained in the bitstream. The tracking filter outputs the code to the sampler circuit in response to the tracking filter updating the code.
Claims20
An apparatus comprising:
- a sampler circuit configured to:
- convert, in response to receiving a first code, the first code into a reference signal and
- produce, in response to comparing an input signal to the reference signal, a bitstream;
- and
- a tracking filter configured to:
- update, upon receiving the bitstream from the sampler circuit, the first code using information contained in the bitstream, and
- output, in response to updating the first code, the first code to the sampler circuit.

A method comprising:
- converting, by a sampler circuit, a first code into a reference signal in response to receiving the first code;
- producing, by the sampler circuit, a bitstream in response to comparing an input signal to the reference signal;
- updating, by a tracking filter upon receiving the bitstream from the sampler circuit, the first code using information contained in the bitstream;
- and
- outputting, by the tracking filter in response to updating the first code, the first code to the sampler circuit.
