A 10-MHz BW 77.3-dB SNDR 640-MS/s GRO-Based CT MASH Delta Sigma Modulator

Honarparvar, Mohammad Rosa Utrera, José Manuel de la Sawan, Mohammad

We present in this brief a novel multi-stage noiseshaping (MASH) 3-1 continuous-time (CT) delta-sigma modulator (M) with gated ring oscillator based quantizers (GROQs) in both stages of the cascade. The use of GROQs increases the linearity performance with respect to the conventional voltage controlled oscillator based quantizers (VCOQs) and...

A 0.9-V 100-mu W Feedforward Adder-Less Inverter-Based MASH Delta Sigma Modulator With 91-dB Dynamic Range and 20-kHz Bandwidth

Honarparvar, Mohammad Rosa Utrera, José Manuel de la

A 0.9-V ΔΣ modulator integrated into a 0.18-μm CMOS technology for digitizing signals in low-power devices is presented in this paper. To do so, a cascade (multistage noise shaping) architecture based on an adder-less feedforward structure is proposed. The proposed modulator has a unity signal transfer function in both stages of the modulator...
