Second order intercept point (ip2) calibration for wireless receivers


Ip2 calibration efficiency can be improved by passing the calibration signal through the transceiver's duplexer instead of inserting the calibration signal directly onto transceivers receive circuit. Passing the calibration signal through the duplexer may reduce ip2 calibration periods for transceivers having less-permeable duplexers, or duplexers that provide better than average separation between the rx and tx circuits.

Programmable mixed-signal input/output (io)


Techniques are described for providing highly integrated and configurable io ports for integrated circuits that can be individually configured for a variety of general purpose digital or analog functions, such as multiple channel analog-to-digital converters (adc), multiple channel digital-to-analog converters (dac), multiplexers, gpios, analog switches, switch and multiplexers, digital logic level translators, comparators, temperature sensors and relays, and so forth. The configurations of individual ports can be set by a configuration register that can, for instance, designate the function and voltage range of the port without impacting the other ports.
