Abstract

In this paper a 4-bit expandable algorithmic Analog-to-Digital Converter has been implemented. It is based on current mode technique. The Analog-to-Digital Converter has been implemented for 4-bits here but can be easily expanded for higher number of bits using the algorithm presented here. The converter uses a current comparator. We have simulated two popular structures of current comparators that can be used to implement this Analog-to-digital Converter. The circuit has been implemented using 0.18 μm CMOS technology with a supply voltage of 1.8V.
