This paper describes an architecture for stable high-order 61 modulation. The architecture is based on a hybrid 61 modulator, wherein hybrid integrators replace conventional analog integrators. The hybrid integrator, which is a combination of an analog integrator and a digital integrator, offers an increased dynamic range and helps make the resulting high-order 61 modulator stable. However, the hybrid 61 modulator relies on precise matching of analog and digital paths. In this paper, adoi:10.1109/tcsi.2005.846229 fatcat:ljqnged4bjgdtkw3iln2axghsi
