A band-pass clock distribution circuit includes a clock tree circuit including at least one clock buffer circuit. The clock tree circuit may be configured to receive a first clock signal from a clock generator circuit and to generate a second clock signal based on the first clock signal. A band-pass filter may be configured to receive the second clock signal and to provide a third clock signal to one or more load circuits. The band-pass filter includes a filtering resonant network including a first inductor and a second inductor coupled to one another at a center tap. The filtering resonant network is configurable to resonate with a parasitic capacitance associated with the one or more load circuits. A portion of the band-pass filter is integrated with the clock tree circuit.
