    This paper presents an algorithmic analog-to-digital converter (ADC), which is based on gray coding. The realization method makes use of the De Morgan's law-based two-input minimum circuit, which performs a low-distortion in the transfer characteristic. The proposed ADC with the low supply voltage is simple, small in size and suitable for implementing a high-resolution ADC. The performances of the proposed circuit were studied using the PSPICE analog simulation program. The simulation results verified the circuit performances are agreed with the expected values.
