Abstract
An approach to building a multi-channel digital-analog system is proposed, in which, unlike the known ones, a code-current converter, a controlled current generator, and also a current communication block are used. For a given accuracy, this saves on the analog system equipment. It has been shown that the proposed principle of building a controlled current source in the form of a highly linear push-pull amplifier – current scalar on bipolar transistors with a grounded load – has a high output resistance and wide bandwidth, which allows the use of current switching to implement the multi-channel system mode.
