analog to digital converter and method of analog to digital conversion.

摘要

Embodiments of the present invention disclose an analog-digital converter and an analog-to-digital conversion method. The analog-digital converter includes: a clock generator, including M transmission gates, where the M transmission gates are configured to receive a first clock signal that is periodically sent and separately perform gating control on the first clock signal, so as to generate M second clock signals, M is an integer that is greater than or equal to 2, each period of the first clock signal comprises M clock pulses, a period of the M second clock signals is equal to the period of the first clock signal, each period of the M second clock signals includes one clock pulse of the M clock pulses; M ADC channels that are configured in a time interleaving manner, configured to receive one analog signal and separately perform, under the control of the M second clock signals, sampling and analog-to-digital conversion on the analog signal, so as to obtain M digital signals, where each ADC channel is corresponding to one clock signal of the M second clock signals; and an adder, configured to add the M digital signals together in a digital field, so as to obtain a digital output signal.
