Summary:
The delta sigma modulator shows idle tone by zero or DC signal input due to limit cycles. In this study, we attend integrator leakages of double loop delta sigma modulator to suppress the idle tone. From bifurcation and FFT analysis, we observe parameter sets of integrator leak-ages which can suppress idle tone in a signal band.
