    摘要: A high-speed and low power divider includes a ring of four dynamic latches, an interlocking circuit, and four output inverters. Each latch has a first dynamic node M and a second dynamic node N. The interlocking circuit is coupled to the M nodes. Based on one or more of the M node signals received, the interlocking circuit selectively controls the logic values on one or more of the M modes such that over time, as the divider is clocked, only one of the signals on the N nodes is low at a given time. The output inverters generate inverted versions of the N node signals that are output from the divider as low phase noise 25% duty cycle output signals I, IB, Q and QB. In one specific example, each latch has eight transistors and no more than eight transistors. The divider recovers quickly and automatically from erroneous state disturbances.

    摘要: A multi-phase frequency divider comprises first and second latches configured to receive a first input clock having a first frequency and a first phase, wherein the second latch receives the inverted first input clock. The first and second latches generate a plurality of output clocks each having a frequency that equals the first frequency divided by a predetermined divider ratio. The plurality of output clocks each have different phases staggered from the first phase. The frequency divider also comprises at least a first delay latch electrically connected between the first and second latches. The first delay latch is configured to generate, based on an output clock generated by the first latch and a second input clock at the first frequency and a second phase, two delayed output clocks. These two delayed output clocks have a frequency that equals the first frequency divided by the predetermined ratio with different staggered phases.

    摘要: The invention pertains to programmable fast logic.The logic gate of the invention comprises two parallel-mounted inverters comprising one transistor and one saturable load. The second inverter is powered through a transistor, the electrode gate of which, linked to the drain, is joined to the drain of the first inverter which may have additional inputs (OR function). A triplet of three series-mounted logic gates comprises a programming input at the third gate, a re-looping output and, in the case of a sequence of triplets, re-looping inputs at the first gate of the first triplet. A programmable logic circuit is obtained by a sequence of series-mounted triplets which are all looped back to the first gate of the sequence. The programming is obtained by placing one or two programming inputs at the logic 0 level.Application: Programmable frequency divider circuits in which the ratios follow one another, one by one.

    摘要: A 1.2 .mu.m CMOS binary counter having a 200 MHz clock rate comprises a 4-bit counting section that may be concatenated in multiple 4-bit sections. Each bit stage within a 4-bit counter section uses the current state of such stage to determine what happens in the next stage. Each 4-bit section performs the counting function through a successive process of additions of a lowest order carry-bit input. A count enable signal serves to enable the count process as well as serving as a carry-bit input to a first stage. Count enable effects a counter reset when in a logic "zero" state. Once the count enable is raised to the logic "one" state, the process of counting begins with the rising edge of the first clock pulse. As long as the count enable is maintained, counting continues. When the count enable is reduced to a "zero" state, counting is terminated, with a counter reset occurring on the next sequential rising edge of the clock.
