Gated Oscillator Starts Without Delay (.PDF Download)

Sept. 1, 2020

Gated oscillators always present the typical problem of having a delay when a digital input control signal enables its oscillation. This delay happens because the timing capacitor starts discharging from Vdd to start oscillating between two thresholds points known as Vt+, and Vt-. This causes the oscillator to have a time delay before it starts oscillating at its expected base frequency. The delay affects precision in timing measurements.
