摘要：【中文】栅压自举开关作为高速模数转换器的最前端，是采样保持电路中至关重要的一个部分，负责对输入的模拟信号进行采样和保持。采样开关的性能决定着整个模数转换器所能达到的最高的分辨率和采样速率。传统的栅压自举开关由于结构的原因，其线性度和采样率上都不足以应用于高速ADC的应用当中。本发明提出了一种应用于高速模数转换器的栅压自举开关，该自举开关在采样时设计有两个并行的路径，使得在采样开始时栅压能够更快的被拉升到预想的高电位，环路的导通电阻变小，使输出能够在更短的时间内开始跟随输入信号，并且由于结构的优化，该开关的寄生电容也得到相应的减小。这种设计使得该栅压自举开关能够实现更高的采样率和更好的线性度，从而非常适用在高速的模数转换器当中。 【EN】The gate voltage bootstrapped switch is the most front end of the high-speed analog-to-digital converter, is a vital part in the sample-hold circuit, and is responsible for sampling and holding an input analog signal. The performance of the sampling switch determines the highest resolution and sampling rate that can be achieved by the overall analog-to-digital converter. The traditional grid voltage bootstrap switch is not enough in linearity and sampling rate to be applied to high-speed ADC application due to the structure. The invention provides a grid voltage bootstrap switch applied to a high-speed analog-to-digital converter, which is provided with two parallel paths during sampling, so that the grid voltage can be pulled up to an expected high potential more quickly at the beginning of sampling, the on-resistance of a loop is reduced, the output can start to follow an input signal in a shorter time, and the parasitic capacitance of the switch is correspondingly reduced due to the optimization of the structure. The design enables the grid voltage bootstrapped switch to achieve a higher sampling rate and better linearity, so that the grid voltage bootstrapped switch is very suitable for a high-speed analog-to-digital converter.
