—This paper presents the design of three-and nine-stage voltage-controlled ring oscillators that were fabricated in TSMC 0.18-m CMOS technology with oscillation frequencies up to 5.9 GHz. The circuits use a multiple-pass loop architecture and delay stages with cross-coupled FETs to aid in the switching speed and to improve the noise parameters. Measurements(More)
Move over Moses! You've got an honest competitor-finally! If the reader doesn't believe it, then he never has believed it. If he's a believer, then we've got a chance!". Throughout his childhood David Reynolds kept an eye on the past, entranced by family stories from Victorian London, as well as the present. In Swan River he shows how a child's.
Speed and power is the major constraint in modern digital design. We have to design the high speed, less number of transistor as a prime consideration. The low power carry look ahead adder using static CMOS transmission gate logic that overcomes the limitation of series connected pass transistors in the carry propagation path. In this approach it is(More)
