An input inductor or input inductive network is used to improve the performance of circuits working in discrete time domain, especially a sample and hold circuit. Input series inductors resonate with the capacitance at the input of the sample and hold at high frequencies to extend its bandwidth. At high frequencies, the inductors act as high impedance chokes between the termination resistor and the capacitors and thus also improve the input reflection of the chip.
