Provided are integrator circuit topologies that enable continuous integration without reset of the integrator circuit. One such integrator circuit includes a first integrator and a second integrator, each of the two integrators having a non-inverting terminal. Each of the non-inverting terminals is connected to an input node to alternately receive an input current for continuous integrator circuit integration without integrator circuit reset. The inverting terminal of the second integrator can be connected to an inverting terminal of the first integrator. The non-inverting terminal of the second integrator can be connected to an output of the first integrator through a first capacitor, and an output of the second integrator can be connected to a non-inverting terminal of the first integrator through a second capacitor. With such a capacitor connection, the capacitors alternately charge and discharge, based on integrator input current that is alternately directed between the non-inverting terminals of the integrators. |
