CURRENT hlODE SIGNAL PROCESSIYC, CIRCUITS

Many wideband circuit functions can be produced by considering current a s the active parameter rather than voltage. Circuits designed in this way can often outperform by a significant margin the more traditional voltage activated formulations and also open up design opportunities not previously possible. is the use o f a ccurate current mirrors and current conveyors as basic building b locks, neither of which, unfortunately, are y et commercially available as integrated circuits. recent developments in current mode analogue circuit design in order to illustrate the increasing benefits which may be obtained by adopting a current mode approach. The key to a new approach
