Abstract
In certain aspects, a sampler includes a sampling capacitor, a precharge switch coupled to the sampling capacitor, one or more discharge circuits coupled to the sampling capacitor, and a reference-voltage circuit coupled to the sampling capacitor. The reference-voltage circuit is configured to generate a reference voltage based on a supply voltage, and generate a voltage difference between a voltage on the sampling capacitor and the reference voltage.
