Description
technical field [0001] The invention relates to the technical field of signal processing, in particular to a clock voltage boosting circuit. Background technique [0002] In some high-speed and high-precision signal processing and conversion circuits, the analog signal needs to be realized through some switches in the process of being sampled and transmitted. The signal that controls the on-off of the switch is generally a set of clock signals. Under the premise that the characteristics remain unchanged, the higher the high-level voltage of the control signal, the smaller the on-resistance of the switch, so that the speed of the analog signal passing through the switch is accelerated and the distortion of the analog signal is reduced. [0003] The voltage of the switch control signal generated by the current clock voltage boosting circuit is usually related to the voltage of the signal to be sampled. When used in some occasions where the voltage range of the signal to be sa...
