An analog baseband chain for WiMedia MB-OFDM UWB and China UWB standard is presented. The baseband chain consists of a fifth-order chebyshev type low pass filter with two switchable cut-off frequencies. A programmable gain amplifier based on enhanced source degeneration architecture is also included. The chip was fabricated in TSMC 0.13-μ RF CMOS process. Measurement results show that the analog baseband...
An RF Transmitter front-end implemented in 0.18 μm CMOS for WiMedia MB-OFDM UWB is presented in the paper, which consists of a V-I converter, an up modulator, a Differential to Single (D2S) converter, a PA and the divided by 2 divider for the LO carrier generation. The post simulation shows the maximum transmitter linear output power level of -2 dBm (3.1-4.8 GHz band) with 6 dB power control range,...
