Document Type and Number:
Japanese Patent JPS5165546
Kind Code:
A
Abstract:
A D/A conversion circuit has each branch of its resistive binary scaling network energized by a switchable network. Each switchable network employs the internal current paths of an Integrated Circuit (I.C.) solid state device, such as a Complementary-Metal-Oxide Semiconductor-Field-Effect-Transistor (CMOSFET) device, which provides complementary switching action. Each switchable network also employs a Metal-Silicon (M-S) diode, which provides clamping and diode switching actions. By a combination of I.C. device and M-S diode device actions, the following features are achieved in a single circuit: (A) high accuracies, (B) fast setting times and (C) low power consumption. Also disclosed is a cooperating variable D/A reference potential source which achieves temperature compensation.
