ABSTRACT:
Ultra low-power GaAs complementary junction field effect transistors are implemented in the design of complementary integrated circuits using a planar technology in conjunction with multiple and selective ion implantation. Both junction FETs, namely the p and n channel devices, are enhancement mode devices and biased in the forward direction thus leading to the advantageous DCFL (directly coupled field effect transistor logic) with one power supply, low power dissipation and high packing densities, all prerequisites for VLSI (very large scale integration).
