  • Publication number: 20150124360
    Abstract: Described is a low power clamp or driver comprising: an inverter; and a silicon controlled rectifier (SCR) embedded in the inverter such that the SCR is part of the inverter. The clamp offers improved conductance per area and lower leakage current compared to the traditional PMOS-based active rail clamps. The clamp or driver combines a trigger circuit with the inverter-embedded SCR for maximum area efficiency. The clamp or driver also results in less stringent requirements for power ramp rates.

  • Patent number: 8304807
    Abstract: A reduced capacitance diode. A first conductive layer provides conductive interconnects for pad and supply diffusion regions in a diode. A second conductive layer includes a first portion to couple the pad diffusion regions to a pad and a second portion to couple the supply diffusion regions to a voltage supply. Lines of the first and second conductive layers are substantially parallel to each other in a diode region of the diode. Further, for one aspect, a tap for the diode to be coupled to a supply is wider than a minimum width.

  • Patent number: 7483247
    Abstract: A multi-stack power supply clamp circuit for providing electrostatic discharge (ESD) protection to enhance performance of advanced submicron processes is provided. The clamp circuit includes a bias voltage generator with low leakage and high current drive capabilities, and means to lighten current load on the voltage generator through reduced gate leakage. The bias voltage generator includes a differential amplifier. The multi-stack clamp circuit provides voltage-tolerant ESD protection with optimized leakage, reduced sensitivity to operating conditions, and tolerance of increased gate current in new process technologies.

  • Patent number: 7239165
    Abstract: Apparatus and systems, as well as methods and articles, may operate to transmit an initial pulse to a directional coupler, where the initial pulse has an initial amplitude and a timed overshoot of a selected duration. Further activities may include stepping down the initial amplitude to an amplitude approximately equal to the initial amplitude times a mode reflection coefficient squared. A tuning stub may be coupled to a charge line to transmit the initial pulse, and decoupled from the charge line to refrain from receiving an echo pulse associated with the initial pulse.
