Construction of a common ring oscillator

Ring Oscillator

A typical ring oscillator consists of an odd number of NOT gates arranged in a loop, with its output alternating between two voltage levels to represent true and false. These inverters are connected in a series, with the output of the last feeding back to the first. Ring oscillators offer

Voltage controlled oscillator

A voltage-controlled oscillator (VCO) is an electronic oscillator whose output frequency is determined by an input voltage. Frequency is the rate at which the phase changes. A voltage-controlled oscillator enables adjustments to this rate of phase change. Usually, VCOs are derived from known oscillator circuits. Various applications include telecommunications, signal
