The advances in wireless technology have made the transfer or sharing of information simple and efficient thereby maximizing its impact to society around the globe. Due to these advances more memory space is required to store such a large transfer of information. This can only be done by reducing the device size which means scaling of MOS transistor to deep submicron levels. The most important part of wireless technology is the wireless trans-receiver. Its role is to transmit or receive the information to (or from) the wireless device. In the wireless trans-receiver, the frequency synthesizer is responsible for generating a stable output frequency which is used further to mix the received signal down to lower frequencies and vice-versa. This stable output frequency is generated by using Phase Locked Loop (PLL). While working at high frequency at the range of 12GHz to 40 GHz, where the operation is carried out at a very high speed and the coverage is done with the multiple beams, the circuits used at high frequency should be compatible with high speed. So, in this paper one very basic component which is the heart of communication system i.e., VCO is studied and the design parameters has been listed in this paper.

“…An oscillator which operates under a low power supply voltage is desired because a low voltage oscillator is suitable for a fine CMOS process and some applications which are powered by a small energy harvester, such as a photovoltaic cell and a thermoelectric element. LC oscillators [1]- [3] and ring oscillators [4]- [8] have been widely used in many integrated circuits. A ring oscillator is known as a oscillator which is suitable for low voltage operation.…”

This paper proposes a novel high frequency ring oscillator. The proposed ring oscillator consists of CMOS inverters which use simple capacitor based level shift circuits. The level shift circuit consists of only a capacitor and a MOSFET. Its power consumption is ideally zero. Thanks to the level shift circuits, transconductance and drain conductance of MOSFETs in CMOS inverters increase and high oscillation frequency is achieved. Validity of the proposed method is confirmed by simulations. The simulation results show that oscillation frequency of the proposed circuit is 2.7 times as high as that of conventional circuit.
