Abstract

A Digital RF receiver front-end with wideband operation capability is presented for m-WiMAX application. By employing sampling mixer and discrete-time filter, the receiver operates in charge domain. In addition to flexibility of the discrete-time (DT) filter, the new Non-Decimation Finite Impulse Response (FIR) filter can be cascaded to a conventional FIR filter. And we can easily increase the order of the sincⁿ-type filtering response and achieve wideband signal process capability. The designed receiver front-end is implemented by IBM 0.13-μm RF CMOS process. The chip satisfies the m-WiMAX specification with 26.63mA from a 1.5-V supply voltage for the total system.
