Abstract: Two kinds of novel single electron analog to digital converter (ADC) and digital to analog converter (DAC) circuits that consist of single electron transistors (SET) and MOS transistors are proposed.The hybrid ADC and DAC circuits have advantages as follows: large load capability;operate at room temperature;low power dissipation.The hybrid SET and MOS transistor ADC/DAC circuits are simulated.The simulation results demonstrate that the circuits can perform data conversion well at room temperature.The sampling frequency can reach 100MHz and the power dissipation is about 0.1μW.
