Abstract
A low-noise filter for a wireless receiver is disclosed. The low-noise filter comprises an amplifier and a filter comprising a frequency dependent negative resistance implemented using a general impedance converter to realize a bi-quad filter. The low-noise filter is implemented such that noise generated by the filter when an in-band signal is processed is prevented from appearing at the output of the amplifier stage.
