Abstract: A digital to analog conversion, DAC, device for converting digital signals to analog signals comprises a RF output for outputting the analog signals, a thermometer segment comprising a first number of data slices and a second number calibration slices, and a calibration controller, which electrically disconnects one of the data slices from the RF output and at the same time connects one of the calibration slices to the RF output as replacement slice for the respective data slice and performs a calibration of the disconnected data slice.

Abstract: The invention relates to a digital to analog converter and a method for a digital to analog conversion, wherein the digital to analog converter comprises at least one analog output cell configured to selectively generate a partial analog signal in response to a partial digital input signal. The analog output cell comprises an analog output switching unit that comprises a current source connected in series to a first node of a retiming switch and a first switch element as well as a second switching element, both connected with respect to first nodes in parallel to a second node of the retiming switch and a switching logic configured to regulate the transmission of said partial analog signal to an analog cell output.

Abstract: An OFDM receiver having an analog multiplier based I-Q channelizing filter, samples and holds consecutive analog I-Q samples of an I-Q baseband, the I-Q basebands having OFDM sub-channels. A lattice of analog I-Q multipliers and analog I-Q summers concurrently receives the held analog I-Q samples, performs analog I-Q multiplications and analog I-Q additions to concurrently generate a plurality of analog I-Q output signals, representing an N-point discrete Fourier transform of the held analog samples, the I-Q signals having relative phase and magnitude representing bits in the OFDM sub-channels. The phase and magnitude may represent QPSK. Optionally, a phase shift decoder receives the analog transform I-Q output signals and generates a corresponding binary bit data.
