Abstract:
1. A signal conversion circuit, comprising: a reference voltage generator configured to receive a reference voltage and generate a plurality of reference voltage signals according to the reference voltage signal; a clock generator configured to receive a clock signal and generate a plurality of clock signals according to the clock signal; a first conversion unit, coupled to each of the plurality of reference voltage signals from the reference voltage generator and to each of the plurality of clock signals from the clock generator, the first conversion unit configured to convert a first signal to a second signal according to one of the reference voltage signals and one of the clock signals; and a second conversion unit, coupled to each of the plurality of reference voltage signals from the same reference voltage generator and to each of the plurality of clock signals from the same clock generator, for converting a third signal to a fourth signal according to the same one of the reference voltage signals and the same one of the clock signals.
