Analog to digital converters are used in extremely many applications to convert real world signals into digital words. The converter presented in this paper, is designed for a cellular nonlinear network type system, where A/D converters are included in each cell to transform the gray scale value to be stored in a 6 bit SRAM memory bank. Because of this, the converter structure should have small silicon area, low power consumption and easy controlling. Presented ADC fulfills these requirements.
