| Abstract(in English) | We propose Current Controlled MOS Current Mode Logic (CC-MCML) and have succeeded in fabricating CC-MCML with 180nm CMOS technology for the first time. The performance stability of the CC-MCML inverter on 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 because CC-MCML is one type of differential circuit. It is shown that when the threshold voltage of NMOS fluctuates from -70mV to 50mV, and threshold voltage of PMOS fluctuates from -60mV to 60mV, the CC-MCML technique is able to suppress ΔV_B within only 45mV where as the conventional MCML technique caused a maximum ΔV_B of 395mV. In this paper, it is verified for the first time that the proposed CC-MCML is more tolerant against the fluctuations of threshold voltages than the conventional MCML. |
