摘要
The delta sigma modulator has a loop filter (SF(z)) in the modulator circuit consisting of a single resonator circuit. The signal is supplied only at one point into the resonator circuit, and runs through only one integrator to the output. The loop filter is a system of half order with poles at z = 1 without resonator coefficients.
