In this paper, the design and analysis of dual-mode numerically controlled oscillators (NCO) based oscillator frequency Modulation is implemented. Initially, input given to analog digital (ADC) converter. This will change from After that, pulse skipping mode (PSM) logic proportional integral (PI) are applied converted data. applying PSM logic, data directly transferred connection block. The blo...

In this paper, a new CMOS current-mode single input and multi-outputs (SIMO) universal filter and quadrature oscillator with a similar circuit are proposed. The circuits only consist of three Current differencing transconductance amplifiers (CDTA) and two grounded capacitors, which are resistorless, and they are suitable for monolithic integration. The universal filter uses minimum CDTAs and pa...

The frequency of a voltage-controlled oscillator (VCO) varies with the voltage applied to its tuning port. Operating in a phase-locked loop (PLL), the VCO provides a stable local oscillator (LO) for frequency conversion in superheterodyne receivers. VCOs are also used in transmit chains, where they upconvert the baseband signal to a radio frequency (RF) suitable for transmission over the airwav...

The dynamical behaviour of the forced escape oscillator, which depends on the parameter values we considered, have been studied numerically using the techniques of phase portraits and Poincar'{e} sections. Also, we employed perturbation methods such as Lindstedt's method to obtain the frequency-amplitude relation of escape oscillator.

Voltage controlled Oscillators or Ring Oscillators are crucial components in any timing and memory circuits. The goal of this paper is to do physical design for a high speed, low power consumption multistage high performance ring oscillator circuit based on 300 nm CMOS technology which provides frequency of high order (KHz). This oscillator is used for high speed wireless communication applicat...

The bouncing gaits of terrestrial animals (hopping, running, trotting) can be modeled as a hybrid dynamic system, with spring-mass dynamics during stance and ballistic motion during the aerial phase. We used a simple hopping robot controlled by an artificial neural oscillator to test the ability of the neural oscillator to adaptively drive this hybrid dynamic system. The robot had a single join...
