摘要： SAR ADC and sampling method based on single-channel TIS. The SAR ADC comprises: a capacitor array comprising a weight capacitor and a compensation capacitor, a first switch array, a second switch array, a channel switch group and a sampling switch; when in a sampling state: a lower plate of the weight capacitor is connected to an input voltage by means of the first switch array, and an upper plate of the capacitor array is connected to a common mode voltage by the sampling switch and the channel switch group; when in a successive approximation state: the lower plate of the weight capacitor is connected to a reference voltage by the second switch array. Input signals are sampled by using a unified to sampling switch, which solves the problem in the traditional technology that sampling moments are mismatched due to different sampling signals in each time-interleaved channel.

摘要： A high-speed low-power-consumption trigger, which comprises a control signal generation circuit, an enabling unit, and a latch structure. The latch structure comprises two input ends, two output ends, two enabling ends, a second enabling end, and a ground end. The enabling unit comprises two enabling circuits. An output signal X of the control signal generation circuit and an external control signal D serve as input signals of the first enabling circuit. An output end of the first enabling circuit is connected to the first enabling end. The output signal X of the control signal generation circuit and a phase-inverted signal DB of the external control signal D serve as input signals of the second enabling circuit. An output end of the second enabling circuit is connected to the second enabling end.
