A new type of analog-to-digital converter (ADC), which consists of an electrooptic light modulator and electronic diode circuits, is proposed. This device allows direct translation of an analog signal into a Gray code with high speed and high resolution. It is demonstrated that an analog signal with a 60-V P–P voltage and a frequency of 11 MHz can be translated into 3 bits in a Gray code by this ADC.
