  • Patent number: 7733169
    Abstract: An operational amplifier (1B) amplifies an input signal (Vin) to produce an output signal (Vout), and includes a 3-stage amplifier (1C) including a first amplifier stage (2) receiving the input signal, a second amplifier stage (3) driven by the first amplifier stage (2), and a third amplifier stage (4) driven by the second amplifier stage to produce the output signal. A slew detection current (Idetect) is generated when the input signal (Vin) exceeds a certain magnitude, and is converted to a control signal (41) that operates a switch (MN0) to short-circuit output conductors of the first amplifier stage to prevent signal charge from building up on capacitances associated with the output of the first amplifier stage during slewing. The three stage amplifier can be a chopper-stabilized, notch-filtered amplifier.

  • Publication number: 20100105319
    Abstract: A redriver chip is inserted between a transmitter chip and a receiver chip and re-drives differential signals from the transmitter chip to the receiver chip. The redriver chip has switched output termination that switches to a high value to detect far-end termination at the receiver chip, and to a low value for signaling. An output detector detects when the receiver chip has termination to ground and enables switched input termination to provide termination to ground on the lines back to the transmitter chip so that the far-end termination on the receiver chip is mirrored back to the transmitter chip, hiding the redriver chip. An input signal detector detects when the transmitter chip begins signaling and enables an equalizer, limiter, pre-driver, and output stage to re-drive the signals to the receiver chip. The input signal detector also causes the switched output termination to switch to the low value termination for signaling.

  • Publication number: 20080257427
    Abstract: A regulator comprises a regulator valve and an actuator. The regulator valve comprises a valve body equipped with a customized valve port. That is, the valve seat is designed to have a customized seat height depending on a diameter of an orifice through the valve port, a longitudinal dimension of an orifice through the valve port, and/or a flow capacity of the valve port. Such a design advantageously maximizes the efficiency at which gas flows through the regulator. The actuator is coupled to the valve body and comprises a valve disc disposed within the valve body and adapted for displacement between a closed position engaging the valve seat and an open position spaced from the valve seat.

  • Patent number: 7391251
    Abstract: An adjustable-delay filter performs wave shaping to emulate pre-emphasis or de-emphasis of transmission-line signals. The adjustable-delay filter uses analog components and does not need a clock. The receiver does not have to recover a bit-clock from the data stream, eliminating a clock recovery circuit. An input buffer receives the input signal and drives current to a summer and to an adjustable delay. The adjustable delay inverts and delays the current and drives a delayed, inverted current to the summer. The summer combines the delayed, inverted current and the current from the input buffer to generate an output signal. The delay time of the adjustable delay can be programmed by a user and is less than the bit period. After a signal transition, the output signal initially spikes higher, then falls back to a nominal level after the delay time has expired. The initial signal spike emulates de-emphasis or pre-emphasis.

  • Publication number: 20080129216
    Abstract: An anti-striation circuit employs an inverter topology including a pair of electronic switches (Q, M) that are switched between a conducting state and a nonconducting state in an alternating manner to apply an asymmetrical voltage waveform across one or more lamp (LP) to thereby control a flow of an asymmetrical current waveform (iacc) through lamps (LP). To eliminate, if not minimize, visible striations in the lamp(s) (LP), the impedances of an asymmetrical driver as connected to the control inputs (B, G) of the electronic switches (Q, M) may be unequal, and/or the impedances of an asymmetrical driver as connected to the current paths (C-E, D-S) of the electronic switches (Q, M) may be unequal. Additionally, the current gains of the electronic switches (Q, M) may be unequal, and a DC current may flow through the lamp(s) (LP).

  • Patent number: 7375563
    Abstract: A clock generator corrects the duty cycle of an input clock. The input clock has a poor duty cycle such as less than 50%. The input clock is applied to a phase detector of a phase-locked loop (PLL). A voltage-controlled oscillator (VCO) of the PLL drives a feedback clock that is also applied to the phase detector. An edge-triggered set-reset SR flip-flop generates a duty-cycle-corrected output clock. The SR flip-flop is set by the leading edge of the input clock, but is reset by the trailing edge of the feedback clock. The VCO generates the feedback clock with the desired duty cycle, such as 50%. The leading edge of the output clock is generated by the input clock, avoiding noise generated by the PLL, while the trailing edge of the output clock is generated by the feedback clock and has PLL noise, but corrects for the desired duty cycle.

  • Patent number: 7375585
    Abstract: An operational amplifier having a wide input common mode voltage range includes first (2) and second (3) differential input transistor pairs coupled to first (14) and second (15) tail current transistors. At least one of the first and second tail current transistor pairs is controlled by a common mode control circuit (4). A gate of the first tail current transistor (14) is coupled to the common mode control circuit (4) to turn the first tail current transistor on and to turn the second tail current transistor off when the common mode input voltage is below a common mode threshold voltage (CMTHR). A folded cascode stage (5) is driven by the first and second differential input transistor pairs.
