Abstract-In this paper, we study the operation of MOS current-mode logic (MCML) gates at lower-than-nominal supply voltages. We show that power can be traded for speed by reducing the supply voltage below the nominal value, while the powerdelay product stays nearly constant. We propose a negative bias strategy that enables the gates to operate at maximum speed with a reduced supply voltage, thus achieving a power saving of up to 35% at no cost for speed. Comparison with CMOS logic style are presented for three different technology nodes (0.25µm, 0.18µm and 0.13µm CMOS).

Abstract-In this work, the authors present a fully integrated, fully differential amplifier operating at 79 GHz using a highspeed Si/SiGe hetero-bipolar technology. This amplifier needs a single supply voltage and shows high performance such as high gain, excellent reverse isolation and low power consumption (90 mW at 3 V supply voltage). This result was achieved by using multi-stage cascode topology and a thin-film microstrip line based design. In addition, the frequency of operation can be easily adjusted within a wide range by changing the length of the matching network (by using focused ion beam or ultrasonic manipulator). A simple but efficient layout technique was used to easily measure single-endedly the differential integrated circuit, also at these high frequencies.

A simple generic interconnect architecture is presented to allow effective cancellation of inductive and capacitive noise in high-speed on-chip interconnect lines. The approach is based on the principle of constructing periodically twisted differential line pairs for parallel interconnect segments in order to eliminate the mutual coupling influences. Detailed simulations show that the twisted-differential lines (TDL) provide high-speed and crosstalk-immnune interconnects, compared to single-ended and differential lines.
