Abstract
A radio-frequency (RF) apparatus includes a wideband receive (RX) impedance matching circuit to provide a received differential RF signal to RF receive circuitry. The wideband RX impedance matching circuit includes first and second inductors to receive the differential RF signal. The wideband RX impedance matching circuit further includes a third inductor coupled across an input o the RF receive circuitry. The third inductor performs the functionality of a capacitor having a negative capacitance value.
