In this paper, the authors present a design of a minimum phase noise current controlled oscillator in CMOS technology. Owing to their high degree of controllability, the second generation current ...

Sine-wave oscillators such as the Wien-bridge, state-variable, or quadrature oscillators, have an inherently undefined amplitude. Ideally, the poles of their feedback loop are on the jω-axis and the ...

This circuit design for a current-mode analog multiplier/ divider is based on current-controlled conveyors (CCCII) and a second-generation current conveyor (CCII). No passive components are used.

Voltage-controlled oscillators (VCOs) are pivotal components in modern communications and signal processing, where their ability to generate a stable yet tunable signal is paramount. The performance ...

Voltage-controlled oscillator-based analog-to-digital converters (VCO-based ADCs) represent an emerging class of digitisation circuits that harness the frequency-modulating properties of VCOs to ...

Last session, we use the cheap and cheerful 4046 Phase-locked Loop chip as a simple voltage-controlled oscillator (VCO). It was dead simple, in fact, because the chip has a VCO already built in. There ...

Fairchild Semiconductor FAN7621 resonant controller simplifies design, reduces bill of materials and provides advanced protection functions. For power designers of LCD and PDP TVs, servers, game ...

The charge pump has many applications. While we generally think of power supply applications, it is also very useful in this voltage controlled oscillator. This VCO has a number of useful features ...
