Description
Summary:In this paper, the electrical circuit scheme for the Bit-Oriented A/D converter compatible with most CMOS process technologies is proposed. In order to overcome the problems of CMOS resistances implementation, further current is used as a processing signal. The most important factors affecting conversion resolution and speed are discussed. It is pointed out that a 3-/spl mu/m CMOS implementation of bit oriented A/D converter can achieve 8-bit resolution to maintain an absolute current error of half LSB. The bit-oriented converter can operate at a sampling rate of 8 MHz. The simple structure of the converter can give rise to other digital codes through variation of the reference voltages and current source connections.< >
