A differential ring voltage‐controlled oscillator (DRVCO) is proposed in this paper as one of
the critical blocks in communication systems. It consists of four stages of delay cells …

In this brief, different characteristics of current starved ring oscillator (CSRO) circuits are
investigated and four new designs are proposed. A new parameter, known as phase noise …

The objective of the proposed work is to demonstrate the use of a hybrid approach for the
design of a voltage-controlled oscillator (VCO) which can lead to higher performance. The …

Abstract The Ring Oscillator (RO) is a ubiquitous element in the high-speed Phase Locked
Loop (PLL) to decide the output frequency for timing controls. Since Digitally Controlled Ring …

This letter presents a study of quadrature voltage controlled oscillators (V COs) and
investigates the performance of existing architectures. Traditionally, even-phased ring …

In recent years, the use of wireless transmission has increased tremendously. In these
systems, voltage-controlled oscillators (VCO) are commonly used as clock generators for …

In this study, a new general expression for the frequency of a SERO is constructed, which
includes two additional variables, Kd and Rw, and improves upon the traditional equations …

In this paper, design of a power-efficient single ended ring voltage controlled oscillator
(VCO) is proposed which utilizes pseudo-NMOS logic with a split-load topology to achieve …
