Consider the "Deboo" Single-Supply Integrator

Abstract: The "Deboo" Integrator simplifies the use of single-supplies by ground-referencing both the input and
the output.


The design of standard inverting integrators is simple when bipolar supplies are available, but it's cumbersome
with a unipolar supply. To allow adequate headroom for the output, the circuit must be biased away from
ground, often at half the supply voltage. Because neither input nor output is referenced to ground, the design is
awkward and often impractical.

One solution is a Howland current source
