Abstract

Embodiments of the present invention include circuits and methods with wide bandwidths. In one embodiment, parasitic capacitances of the output of a first stage and the input of a second stage are included in a network. The output of the first stage is coupled to the input of the network, and the input of the second stage is coupled to an intermediate node of the network. In one embodiment, the parasitic capacitance of the second stage is the largest capacitance in the network. In another embodiment, passive networks are coupled to the outputs of a stage, and one or more current injection circuits may be used to extend the bandwidth of the circuit.
