The Design And Simulation Of The Hybrid Circuits With Single Electron Transistors And MOS

With the development of integrated circuit(IC), there are some problems in the traditional integrated circuit. Two solution ways are found: (1) Developing in the direction of Moore law ;(2) Exploring new devices and circuits to replace the conventional MOS devices and circuits, such as single electron transistors (SETs) and circuits.We proposed two kinds of novel single electron analog-digital conversion (ADC) and digital-analog conversion (DAC) circuits that consist of single electron transistors (SETs) and metal-oxide-semiconductor (MOS) transistors. The SET/MOS hybrid ADC and DAC circuits possess the merits of the SET circuit and the MOS circuit. The SPICE macro-modeling code is used for the simulation of the SET/MOS hybrid ADC and DAC circuits. We simulate the performances of the SET/MOS hybrid 6-bit ADC and 2-bit DAC circuits by using H-SPICE simulator. The simulation results demonstrate that the hybrid circuits can perform analog-digital and digital-analog data conversion well at room temperature. The hybrid ADC and DAC circuits have advantages as follows: 1) Compared with conventional CMOS ADC and DAC circuits, the architectures of the circuits are simpler and the power dissipation of the circuits are lower than uW; 2) Compared with single electron transistor ADC and DAC circuits, the circuits have much larger load capability and the circuits can be realized with modern silicon techniques; 3) The data conversion rate of the circuits can exceed 100Mhz; 4) They have good linearity; 5) The resolution of the ADC and DAC circuits can be increased by the pipeline architecture and cascade weight capacitance architecture, respectively.
