dc.description.abstract | This thesis presents a 12-bit ΣΔ ADC design on 45 nm CMOS technology for MEMS sensor applications. The design was performed using Virtuoso Cadence tools. The circuit is composed by a first-order ΣΔ Modulator, a CIC filter, and a Decimator. The first-order ΣΔ Modulator having an oversampling ratio K=128 is developed implementing the switched-capacitor technique. The first-order ΣΔ Modulator is composed by an integrator, a comparator, and a 1-bit DAC. Simulation results show how the Modulator changes the output transitions frequency depending on the input voltage value, being K=128 the best tradeoff between the number of modulations and circuit complexity. The physical design of this block is fully customized. For the digital filter and decimator blocks, a third-order Cascaded Integrator Comb (CIC) filter is developed as a Verilog macro model to test and measure the transient and spectral response of the ADC, as well as its main Figures of Merit. | |
