Abstract

Certain aspects of the present disclosure provide apparatus and techniques for analog-to-digital conversion using a time-to-digital converter (TDC). For example, certain aspects provide a quantizer using a TDC. The quantizer may include at least one first capacitive element and a set of switches configured to selectively couple a first terminal and a second terminal of the at least one first capacitive element to at least one input voltage source. The TDC may also include a reference voltage source, at least one switch coupled between the second terminal of the at least one first capacitive element and an output of the reference voltage source, a current source selectively coupled to the first terminal of the at least one first capacitive element, and a voltage sense circuit coupled to the first terminal of the at least one first capacitive element.
