Design of current steering logic CMOS circuit

The current-mode CMOS technology has many positive identities, while traditional current-mode CMOS circuits designing methods is comparatively more complex than voltage-mode CMOS. In this paper, using threshold logic, a current-mode CMOS circuits designing method based on spectral techniques is proposed. The proposed method is capable of designing combinational logic current-mode CMOS circuits. The sequential logic current-mode CMOS circuits can also be designed with the designed combinational logic current-mode CMOS circuit. The designed circuit is steered only by current signals. By using both simulations and real circuit tests, we proved the effectiveness of the proposed circuit designing method. Using HSPICE simulations, the designed circuit is proven to have advantages including lower circuit power consumption and higher stability of the current through power supply compared with voltage-mode CMOS and other main current-mode CMOS circuits, and the designed circuits require less control signals than other major current-mode CMOS circuits.
