In this paper, a passive down mixer is proposed, which is well suited for short-channel field-effect transistor technologies. The authors believe that this is the first drain-pumped transconductance mixer that requires no dc supply power. The monolithic microwave integrated circuit (MMIC) is fabricated using digital 90-nm silicon-on-insulator CMOS(More)
Very low gate delays of 7.7 ps at 1 V supply and 4.7 ps at 2 V supply have been achieved for CMOS inverters fabricated on a 90 nm silicon on insulator technology. The results are measured with an optimised CMOS ring oscillator. These are believed to be the lowest gate delays reported to date for CMOS inverters at room temperature. Introduction: The increase(More)
—A sampling latch for full-, half and quarter-rate clock and data recovery circuits at data rates of 12.5 Gb/s, 20 Gb/s and 25 Gb/s, respectively, achieving a bit error rate lower than 10-12 is presented. The circuit is implemented in a 90-nm CMOS technology. The master-slave D-FF including peaking inductors consumes only 1 mW of power and requires a small(More)
