| چکیده | ||
| This paper, in the first step, introduces a low-power oscillator in the GHz range using the CNFET technology with a Schmitt Trigger, in which the Upper Trigger Point and Lower Trigger Point can be adjusted only through a change in the diameter of the nanotubes of two CNFETs. In this oscillator, the frequency and duty cycle of the output signal can be adjusted via a change in the physical parameters of the transistors and capacitor capacity. The relation of frequency based on Physical parameters is analysed and obtained. The power consumption of the proposed oscillator at 2 GHz frequency is only 2.7 µWatt. The circuit has an output frequency variation range of 50 KHz to 3.5 GHz with a power consumption rate of 0.15 to 12 µwatts in the without offset mode. Through the use of frequency shift in the with offset mode, we can access a wide range of frequency ranges by changing the input voltage. Proposed Circuits are evaluated with the Stanford CNFET Model at 32nm technology in terms of output frequency linear range, power consumption and frequency stability against temperature and process variation and are approved. | ||
