Abstract

In this paper, a theoretical analysis of current-controlled (CC-) MOS current mode logic (MCML) is reported. Furthermore, the circuit performance of the CC-MCML with the auto-detection of threshold voltage (Vth) fluctuation is evaluated. The proposed CC-MCML with the auto-detection of V th fluctuation automatically suppresses the degradation of circuit performance induced by the Vth fluctuations of the transistors automatically, by detecting these fluctuations. When a Vth fluctuation of ±0.1 V occurs on the circuit, the cutoff frequency of the circuit is increased from 0 Hz to 3.5 GHz by using the proposed CC-MCML with the autodetection of Vth fluctuation.
