Does this circuit exist?

Sounds like a simple analogue computing problem

The latter function doesn't have an antiderivative expressable in terms of elementary functions, so the Laplace transform of it isn't likely to be anything nice, hence the circuit is certainly not going to be anything nice...

And it isn't the solution of any linear ODE with constant coefficients, either. You can do it with a dual op amp and a BJT matched quad, at least until the intermediate node saturates, which will be within a few seconds.

Thanks, yes I don't think it can be done easily with R's and C's. It popped up as a solution to a math problem I'm working on and I wondered if there was a corresponding circuit. Of course I could always digitize the impulse response at a high sample rate and run it as an FIR.

You'd run out of bits pretty fast, though.
