Asynchronous type successive approximation register type analog-to-digital converter and the internal clock generator being contained therein

초록

The internal clock generator for disclosing a kind of asynchronous type successive approximation register type analog-to-digital converter and being contained therein.The internal clock generator for being contained in successive approximation register type analog-to-digital converter includes:Test section senses the generation moment of final internal clocking and next external clock and generates rising pulses or falling pulse;And delay block, according to the rising pulses or falling pulse control bias voltage increased or reduced delay time.Asynchronous type successive approximation register type analog-to-digital converter of the invention can make internal clocking and inflection point variation and circuit entirety or local temperature variation independently keep steady operation.
