Summary :

We have succeeded in fabricating 180 nm Current Controlled MOS Current Mode Logic (CC-MCML) and verified the stable circuit operation of 180 nm CC-MCML under threshold voltage fluctuations by measurement. The performance stability of the CC-MCML inverter under the fluctuations of threshold voltage of NMOS and PMOS is evaluated from the viewpoint of diminishing the bias offset voltage ΔV_B. The ΔV_B, that is defined as (base voltage of output waveform) - (base voltage of input waveform), is a key design parameter for differential circuit. It is shown that when the threshold voltage of NMOS fluctuates in the range of 0.53 V to 0.69 V, and threshold voltage of PMOS fluctuates in the range of -0.47 V to -0.67 V, the CC-MCML technique is able to suppress ΔV_B within only 30 mV, where as the conventional MCML technique caused maximum ΔV_B of 1.0 V. In this paper, it is verified for the first time that the fabricated CC-MCML is more tolerant against the fluctuations of threshold voltages than the conventional MCML.
