As electronic products continue to develop, the requirements for the accuracy of integrated circuits continue to increase. Oscillators play a more important role in integrated circuits, and higher requirements are placed on the power consumption as well as the accuracy of oscillators. In this paper, a high-precision and low-power consumption RC oscillator is designed. The oscillator in this paper consists of a bias module and a capacitor charging and discharging module and provides bias current and voltage with temperature coefficient through bandgap to reduce the change of oscillator operating frequency caused by the increase of ambient temperature in traditional oscillators, which improves the oscillator operating state under different temperatures and the accuracy of the oscillator. The single comparator oscillator structure is also designed to effectively eliminate the effect of the dropout voltage on the oscillation period. The oscillator is simulated by using the MGN 0.18 μm process.

“…The acronym SRCO refers to sinusoidal oscillators in which the condition of oscillation (CO) and the frequency of oscillation (FO) both can be independently adjusted (without affecting each other) through separate single variable resistors. The SRCOs have been realized using a variety of active building blocks (ABB) such as the op-amps, operational trans-conductance amplifiers (OTA), [37][38][39] Current Conveyors (CC), 34,40 Current feedback op-amps (CFOA), 35 four-terminal-floating-nullor (FTFN), 41,42 or operational floating amplifiers (OFA) 31,43,44 and many other recently introduced active building blocks. [34][35][36]45 A brief overview of FTFN-based sinusoidal oscillators, with which this paper is concerned, is now in order.…”

In the past, several new active elements have been employed to realize singleresistance-controlled oscillators (SRCO) of which the four-terminal-floatingnullors (FTFN) have attracted considerable attention in the literature. In this paper, an ingenious methodology of deriving single-FTFN-based canonic grounded-capacitor (GC) SRCOs has been presented. It is shown that such oscillators can be systematically evolved from a class of earlier known op-ampbased SRCOs through the application of two theorems pertaining to RC-nullor oscillators published earlier. The presented methodology not only yields all the previously known (four) single-FTFN-based canonic GC SRCOs but also reveals a number of (12) new circuits, which have not been known in the open literature earlier. The viability of the evolved oscillator circuits has been confirmed through SPICE simulations, and some simulation results have been given.
