Abstract: An integrated circuit is described. The integrated circuit comprises a first portion having programmable resources; a second portion having hardened circuits including an analog-to-digital converter circuit configured to receive an input signal and generate an output signal; and a monitor circuit configured to receive an output signal generated by the analog-to-digital converter circuit; wherein the monitor circuit is configurable to control a calibration of the analog-to-digital converter circuit based upon signal characteristics of the output signal generated by the analog-to-digital converter circuit. A method of receiving data in an integrated circuit is also described.

Abstract: An example transmitter includes first and second circuit stages and interface circuits. The first circuit stage is configured to generate modulated signals each having a different carrier frequency from baseband signals. The second circuit stage is configured to generate radio frequency (RF) energy to be radiated by antenna(s). The interface circuits are coupled between the first circuit stage and the second circuit stage. The second circuit stage and the interface circuits are configurable to provide a first mode and a second mode. In the first mode, the second circuit stage provides transmit paths and the interface circuits couple each of the modulated signals to a respective one of the transmit paths. In the second mode, the second circuit stage provides a first transmit path and the interface circuits couple a sum of at least two of the modulated signals to the first transmit path.
