Logic Noise: Playing In Tune With An Exponential VCO

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 ...

10 to 1000 MHz Oscillator

Nowadays, it is no longer necessary to use discrete components to build oscillators. Instead, many manufacturers provide ready-made voltage-controlled oscillator (VCO) ICs that need only a few ...

Voltage-Controlled Oscillator ICs Seek To Replace VCO Modules

Claimed as the industry's first 2.4-GHz fully self-contained VCO ICs, the MAX2750/MAX2751/MAX2752 are designed for use in 2.4-GHz ISM applications, such as 802.11 WLAN, HomeRF, Bluetooth, and ...

Voltage-Controlled Oscillator-Based Analog-to-Digital Converters

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 ...

Low-frequency, voltage-controlled oscillator has adjustable duty cycle

Low-frequency voltage-controlled oscillators (VCOs) can be found in clocks, timers, audio synthesizers, and a variety of other applications. The VCO shown in Figure 1 is based on a simple astable ...
