Through studying the design principles of multi-valued logic circuit and the SABL circuit, this paper presents a design scheme of three-valued counter. Two-valued coding method and SABL circuit characteristics such as complementary output signals and the capacitance coupling effect are integrated to implement the developed scheme. Then, the current compensation circuit is used to keep steady output logic 1, and further to achieve n-bit three-valued counter. Finally, with the parameters of SMIC 0.13μm CMOS device, the SABL three-valued counter is simulated by SPECTRE. The results show that the designed circuit has correct logic function and constant power per clock cycle.
