A 2.8-V Multibit Complex Bandpass ∆ΣADModulator in 0.18μm CMOS
A second-order multibit switched-capacitor (SC) complex bandpass ∆ΣAD modulator has been designed, fabricated and tested for application to low-IF receivers in wireless communication systems. We have employed two new algorithms there to improve the signal-to-noise-and-distortion (SNDR) of the modulator. (i) A complex bandpass filter with I, Q dynamic matching to reduce the mismatch influence be...
متن کاملA Switched-Current Bandpass Delta-Sigma Modulator
An eighth-order switched-current bandpass delta-sigma modulator is described. Simulations indicate that our 1.2pm CMOS implementation will achieve a S N R of 90dB in the band 10 MHzk150 KHz when clocked at 40 MHz. The modulator makes use of a switched-current resonator based on the N-path technique and the resonator employs regulated-cascode current-copiers to simultaneously achieve high speed ...
متن کاملTime-Mode Signal Quantization for Use in Sigma-Delta Modulators
The rapid scaling in modern CMOS technology has motivated the researchers to design new analog-to-digital converter (ADC) architectures that can properly work in lower supply voltage. An exchanging the data quantization procedure from the amplitude to the time domain, can be a promising alternative well adapt with the technology scaling. This paper is going to review the recent development in t...
متن کاملA 50-MHz Multibit Sigma–Delta Modulator for 12-b 2-MHz A/D Conversion
Oversampling techniques offer several advantages for the implementation of high-resolution analog-to-digital (A/D) converters in VLSI technologies. This paper examines the application of oversampling techniques to A/D conversion at rates exceeding 1 MHz. A cascaded multibit sigma-delta (2A) modulator that substantially reduces the oversampling ratio required for 12-b conversion while avoiding s...
متن کاملA 160-MHz Fourth-Order Double-Sampled SC Bandpass Sigma–Delta Modulator
A fully differential double-sampled switchedcapacitor (SC) architecture for a fourth-order bandpass modulator is presented. This architecture is based on a doublesampled SC delay circuit. The effect of opamp nonidealities (finite dc gain and nonzero input capacitance) on the notch frequency of this modulator is analyzed. The modulator is implemented in a 0.5m CMOS technology and operates at a c...
