    Abstract: An Analogue to Digital Converter (ADC) having a Gated Ring Voltage Controlled Oscillator, GRVCO, to generate a phase signal according to an input voltage; and a quantization circuit to generate a quantized phase output signal according. The GRVCO operates in either a first or second mode of operation according to a gating control signal. In the first mode of operation, the GRVCO operates in a VCO mode with gating disabled. In the second mode of operation, the GRVCO operates in a GRVCO mode wherein gating is enabled or disabled according to a gating signal.
