Implementation of on-chip high precision oscillators with RC and LC using digital compensation technique


  • Received: 21 March 2022 Revised: 03 May 2022 Accepted: 26 May 2022 Published: 05 July 2022
  • High precision oscillators became a significant call for both designer and testing engineers. Modern vibrators are being utilized in a variety of circuits, and accessibility to a wide range of frequencies is of the utmost importance in all research establishments. To produce various frequencies, utilizing a single gadget is very challenging for the designers. This article aims to provide the low frequency (RC) oscillator and high frequency (LC) oscillators with various output frequencies on a single chip. The use of both oscillators is necessary due to the fact that there are currently no such devices on the market, which makes it necessary to avoid using bulky recurrence generator hardware in order to facilitate rapid exploration and plausibility research. Here, a RC oscillator with high current accuracy and a LC oscillator with low force have been used to design a voltage controlled oscillator (VCO) IC by utilizing the Cadence 45 nm technology. This particular VCO IC is able to obtain two different frequencies with reasonable precision. Further, execution is completed by utilizing exclusive requirement inconsistent message format designing. This proposed work can be used at both audio frequency and radio frequency ranges from megahertz (MHz) to gigahertz (GHz).
