Abstract
This paper presents one-bit cell supporting input voltage to synthesize triangular-like DC transfer characteristic and digital output of Gray-code algorithmic analog-to-digital converter. The proposed one-bit cell is based on the use of operational conveyors in connection with resistors, diodes, and voltage comparator. An N-bit resolution can be simply realized by cascading the N proposed one-bit cells. Surpassing the previous one-bit cells using operational transconductance amplifiers, the proposed converter affords higher resolution and simpler configuration. The circuit operations of the proposed converter are confirmed through PSPICE simulation and experimental results. ©ICROS.
