Abstract :
Differential-type structures to implement Boolean functions find very interesting applications in self-timed circuits. A novel structure of CMOS differential circuit called Switched Output Differential Structure (SODS) is presented in this paper. This structure has been designed modifying the LOAD circuitry of previously reported differential structures, gaining in terms of transistor-count and area. This cell has been implemented on a standard 1.5 μm technology and has served to assess the structures and compare it with previously reported differential structures. Experimental laboratory results, as well as electrical simulation, show improved timing and power performance, i.e., 470 MHz and 0.46 mW at 50 MHz, respectively, for the buffer-inverter operation, with Vdd=5 V
