<p>An LR polyphase filter (410) implemented with inductors (422, 428) and resistors (424, 426) includes first and second paths, with each path including an inductor coupled to a resistor. The first and second paths receive a first input signal (Vin) and provide first and second output signals (Vout1,Vout2), respectively, which may be in quadrature. For a differential design, the polyphase filter (430) further includes third and fourth paths, which receive a second input signal and provide third and fourth output signals, respectively. The four output signals may be 90 out of phase. The first and second input signals are for a differential input signal. The first and third output signals are for a first differential output signal, and the second and fourth output signals are for a second differential output signal. Each inductor may be implemented with a transmission line.</p> |
