摘要： A transceiver which effectively cancels interference caused by a component (e.g., driver) of a transmitter (contained in the transceiver). The input and output signals of the component are examined to estimate the magnitude of the interference, and the interference is canceled according to the estimate. Accordingly, the component need not be implemented with high accuracy/precision.

摘要： A characteristic is measured on multiple portions of an integrated circuit, and the supply voltage adjusted based on the measurements. In an embodiment, the characteristic corresponds to propagation delay which indicates whether the integrated circuit is implemented with a strong, weak or nominal process corner. In general, the supply voltage can be increased in the case of a weak process corner and decreased in the case of a strong process corner.

摘要： Ensuring sufficient bias current is provided to a portion of a circuit containing low voltage transistors operating with a high supply voltage. Such a sufficient bias current may be ensured by generating a primary bias current from a low supply voltage and a backup bias current from a high supply voltage, and providing the backup bias current as the bias current if the primary bias current is not present. The primary bias current may be provided as the bias current when the low supply voltage is available. Thus, the backup bias current is provided as bias current in case of undesirable supply sequencing.

摘要： An aspect of the present invention provides multiple switches in a transceiver, which enable pins provided for transmission and reception to be connected to either a transmit port or a receive port, as desired during operation. As a result, the transceiver can be auto-configured to connect the specific pin, on which signals are being received, to the receive port. Similarly, the transceiver can be auto-configured to connect the specific pin, on which the signals need to be transmitted, to the transmit port. Various design considerations in providing such switches are also described.
