Low Voltage CMOS op-amp with Rail-to-Rail Input/Output Swing
Abstract--As the supply voltage to a standard CMOS opamp is reduced, the input common mode range and the output swing get reduced drastically. Special biasing circuits have to be u...

A Detection Algorithm for Clipped OFDM Signals Using the IDFT-Matrix
A major drawback of the Orthogonal Frequency Division Multiplex (OFDM) principle is the high dynamic range of the transmit signal. The transmit Power Amplifier (PA) and other ele...
