1. An analog pulse capture circuit, the analog pulse capture circuit comprising:
one or more input sources configured to receive one or more optical signals and generate one or more electrical input signals;
one or more distributed capacitors configured to store a target charge, the one or more distributed capacitors including one or more coplanar waveguides, the one or more coplanar waveguides including one or more top plates and a plurality of bottom plates, at least one top plate of the one or more top plates is arranged coplanar with at least one bottom plate of the plurality of bottom plates, the one or more top plates referenced to a ground plane, the plurality of bottom plates referenced to the ground plane;
one or more amplifiers coupled to the one or more distributed capacitors, the one or more amplifiers including at least one inverting terminal and at least one non-inverting terminal, the one or more amplifiers configured to generate one or more electrical output signals; and
one or more dump switches coupled to the one or more input sources, the one or more dump switches configured to connect the one or more amplifiers to the one or more input sources, the one or more dump switches positioned proximate to the one or more distributed capacitors, the one or more dump switches configured to release the stored target charge of the one or more distributed capacitors.
