摘要： A digital radio transceiver integrated circuit includes MOS transistors with normal threshold voltages in the digital circuits, and with reduced threshold voltages in at least some of the analog RF components. This allows the transceiver to be reduced in size and weight, without requiring performance to be compromised.

摘要： The present invention relates to the generation of a time mean value-free binary signal (O) from an input signal (IN). The device (10) comprises a feed-back loop adjusting the pulse ratio of the output signal by comparing its mean value to the mean value of a time mean value-free reference signal (J) and feeding-back the difference between said two mean values. The mean values are approximated by low pass filtering the binary signal (O) and the reference signal (J) with two filters (8, 7). If the filters (8, 7) are non-linear, the mean values of the filtered signals (S, FJ) can deviate from the mean values of the reference signal (O) and the reference signal (J). By constructing the filters (8, 7) as regards non-linearities, to be equal, the aforementioned discrepancy will be compensated, since the signals will deviate to the same degree from their theoretical values, when time mean value free.
