Abstract in different language: A new sinusoidal oscillator using Carbon Nanotube Field Effect Transistors (CNTFET) based Operational Transconductance Amplifiers (CNOTA) with grounded capacitors is presented in this paper. The proposed current-mode oscillator thus implemented and having grounded capacitor feature, fulfils the need for realizations of systems used in combination with various other systems/ subsystems - both voltage-mode and current mode. It also ensures simplicity in implementation by using a single-ended CNOTA. The analytical model is given for the circuit leading to fulfilment of the condition of oscillation at tuned frequency. The proposed sinusoidal oscillator is primarily used in the field of signal dispensation applications, telecommunication networks, communication-equipment and control modules. The benefits derived from the introduced model are validated by simulation carried out at a supply voltage of ± 1.8V in Cadence virtuoso using spectre model libraries. They are further tested with the aid of 32 nm model of Carbon Nanotube Field Effect Transistor (CNTFET) technology obtained through open source. The proposed design (and the model provided) is found to be in good agreement with the obtained results.
