Abstract

Since current threshold values are easy to control

this paper studies how to realize the threshold controlling in current-mode CMOS circuits.Guided by the switch signal-theory

the operations of current transmission switch used to realize threshold-controlling circuits are established.On this basis

binary and multiple-valued current-mode CMOS adders with threshold-controllable function are designed.A universal design method for current-mode CMOS m-valued adders based on threshold-controllable technique is proposed.By employing the threshold-controlling technique

the construction of the circuits has been simplified considerably

and the performance of the circuits has been improved.HSPICE simulations of transient characteristics using 0.25μm CMOS technology are presented

and the simulated results of energy dissipation are compared.
