Abstract
A wideband digital RF receiver front-end employing a
discrete-time (DT) filter is presented for application to m-WiMAX
(WiBro). By employing a sampling mixer and a DT filter, the re-
ceiver operates in the charge domain. In addition to the flexibility
of the DT filter, the new non-decimation finite impulse response
(NDF) filter can be cascaded to a conventional finite impulse re-
sponse (FIR) filter without the decimation effect. Thus, we can
easily increase the order of the function-type filtering re-
