GaAs MESFET Switched-Current Circuits

The implementation of the switched-current technique using GaAs MESFET technology has been proposed in this chapter, however, further circuit design innovation is still required before the technique can be practically exploited. We believe that the work is an encouraging step towards LSI in GaAs design, specifically for realising the analogue parts such as modulators, integrators, filters, and comparators for mixed mode RF front-end interfaces on pure digital technology.
