| Abstract: | The circuit architecture and mathematical expression for two-step A/D converter are analyzed, based on which a novel two-step high-speeding A/D converter is proposed. In the new architecture, the ADC is designed without the amplifier, which makes the convert speed and precision be improved. The simulation result shows that it has a simple architecture and correct function. |
