  • Data capture window extension circuit
    Patent number: 4550391
    Abstract: A digital data capture window extension circuit utilizing a matched pair of signal detection subcircuits that are activated during alternate cycles of a master read clock. The interleaved operation of the paired subcircuits permits each subcircuit to detect and process an incoming data signal, resulting in an effective overall processing rate twice that of prior art circuitry. The invention therefore permits the reading of data at a high rate using a system clock of the same frequency as the incoming data.

  • Fast digital sample resolution circuit
    Patent number: 4473760
    Abstract: A fast digital sample resolution circuit comprising a dynamic ratioless inverter coupled to a static ratioed inverter, with positive capacitive feedback. A transistor node is precharged to one logic level. Any positive transition of an input signal causes the precharged node to begin discharging, thereby causing a capacitive feedback signal to rapidly reinforce the input signal. The resolution circuit minimizes the probability that its output is an ambiguous logic signal.
