摘要： A bandpass delta sigma truncator that truncates multi-bit digital input signals to digital output signals (24) having a selected number of the most significant data bits of the digital input signals and a method of truncating multi-bit digital signals. The remaining least significant data bits (3) of the input signals are (a) time delayed (26) by a period of time equal to the time between successive input signals and multiplied by a number (30) related to the ratio of a selected frequency to the frequency of the input signals and the results of the multiplication are added (32) to signs extensions (11) of the input signals, and (b) time delayed by a period of time equal to twice the time between successive input signals and after inversion (28) are added (32) to the sign extensions of the input signals.

摘要： An adaptively tuned RF power amplifier includes at least one power amplifier stage that has one or more active elements. A tunable output network is coupled to the power amplifier stage and includes one or more adjustable reactive elements. A mismatch detector detects a tuning mismatch based, at least in part, on one or more signals present within the tunable output network, and supplies one or more mismatch signals indicative of a detected tuning mismatch. A tuning controller, responsive to the one or more mismatch signals, controls one or more of the one or more adjustable reactive elements in the tunable output network so as to control the detected mismatch.
