Low-Power Design Of A Multi-Mode Transceiver

: Recent advances in electronic technology and integration coupled with increasing needs for more services in portable communications favors the development of high performance dual- mode terminals. Here, we present the complete architecture implementation of the GMSK/GFSK modulator/demodulator including the FIR filters design. The main features of the modulator/demodulator and the architectural implementation of FIR filters are described. The interface with ASPIS processor [1] and A/D & D/A converters is also described in detail manner. The whole architecture of the modulator/demodulator was described by VHDL hardware language, synthesised and implemented in Xilinx environment. 1
