摘要:
A differential signaling circuit and a control circuit. The differential signaling circuit includes a first positive driver and a first negative driver. The first negative driver has different impedance than the first positive driver. The first positive driver and the first negative driver together define a first current path between positive and negative power supply terminals. A first output is defined on the first current path intermediate the first positive driver and the first negative driver. The control circuit includes a first driver that drives a transmission line at a first output voltage, a feedback amplifier responsive to the first output voltage to generate a control signal and a metal oxide semiconductor (MOS) driver coupled to the first driver and responsive to the control signal to make impedance of the first driver equivalent to impedance of the transmission line.

Integrated Circuits (ICs) comprising circuits configured to generate a power on reset (POR) pulse are disclosed. An IC comprises a power supply sense circuit configured to generate a sense signal in response to a transition of a power supply signal from a first level to a second level, and a pulse generation circuit coupled with the power supply sense circuit. The pulse generation circuit is configured to generate a power on reset (POR) pulse of a threshold duration based on the sense signal. The IC further includes a reset generation circuit coupled with the pulse generation circuit to receive the POR pulse. The reset generation circuit is configured to generate a reset pulse based on the POR signal and of at least one control signal, where the reset pulse is configured to be utilized to perform a reset of one or more elements of the integrated circuit.
