Integrated circuit binary weighted digital-to-analog converter

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