  • TRANSCEIVER WITH SWITCH CIRCUIT FOR ROUTING DATA FROM RECEIVER TO TRANSMITTER
    Publication number: 20090161740
    Abstract: A transceiver includes a receiver unit including a clock and data recovery unit. The transceiver includes a transmitter unit and a digital core coupled to the receiver unit and the transmitter unit. A switch circuit is positioned after the clock and data recovery unit, and is configured to route data from the receiver unit to the transmitter unit in a test mode of the transceiver.

  • Method and device for switch-on current limiting in push-pull amplifying power stages
    Patent number: 6911866
    Abstract: The invention provides a method for amplification of analog push-pull signals (101a, 101b) by means of a push-pull amplifier output stage (100) which has a first output stage transistor (102a) and a second output stage transistor (102b), with first and second analog push-pull signals (101a, 101b) being applied to the first and second output stage transistors (102a, 102b) and to first and second control transistors (103a, 103b), by which means first and second control currents (104a, 104b) are controlled, furthermore with the second control current (104b) which is controlled by the second control transistor (103b) being mirrored by means of a current mirror device (105) into a mirrored second control current (104c), with the first control current (104a) being compared with a first reference current, with the mirrored second control current (104c) being compared with a second reference current, with reference voltage levels (107a, 107b) which are produced by the comparison processes being logically linked in an
