ABSTRACT:
An integrated circuit digital-to-analog converter circuit of the binary weighted current summing type in which the emitter potentials of the transistor current sources are maintained substantially equal by controlling the voltage differential between the base electrodes of the current source transistors. In one disclosed embodiment, the base electrodes of the transistor current sources are connected to a resistive divider network and the voltage across each of the resistors is maintained substantially equal to (kT/q) ln 2. The disclosed circuit can be used as an alternative to, or in combination with, prior art emitter-scaling techniques.
