Oversampling sigma-delta modulator
 Based on the recently developed MASH (multistage noise shaping) architecture, an improved architecture--uni-MASH which employs the time-division concept for architecture and circuit reuse is proposed. An oversampling sigma-delta modulator having uni-MASH architecture uses a single stage of time- and capacitor-integrator in lieu of multiple stages of integrators, digital-to-analog converters and quantizers used in the MASH architecture. Uni-MASH retains robust stability and high-ordered noise shaping factor of MASH's virtues.
