摘要： In the many microelectronics applications, delays present in circuitry can affect both the design and the function of the circuitry. One example of delays impacting the function of a circuit is a relaxation oscillator, where delays present in comparator circuits and latches can cause its frequency to vary beyond desired ranges. Here, a relaxation circuit with delay compensation is described.

Each equalization path is coupled to at least one of the channels, and a controller has a VGA loop, a crossbar loop, and a driver loop. The AGC loop receives a first reference voltage and provides a gain control signal to the input circuit, and the gain control network comprises a replica of at least one of the equalization paths. The crossbar loop receives a second reference voltage and provides a crossbar control signal to the crossbar.

摘要： In bipolar CMOS or BiCMOS process technologies, drivers (such as mixed mode or hybrid mode drivers) using both bipolar and CMOS transistors (i.e., field effect transistors or FETs) may have undesirable properties, such as reduced speed, ringing, latch-up, or lower electrostatic discharge (ESD) performance. Here, a mixed or hybrid mode driver is provided that employs a current steering circuit (instead of voltages driven differential pair(s) as is done with conventional drivers) to generate pull-down currents that precisely match the voltages in the pull-up portions of driver. It increases the speed and produces smaller output common-mode voltage fluctuation over conventional drivers. Thus, the driver provided here can be produced in BiCMOS process technologies without the undesirable effects of conventional drivers.
