    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (154 KB)

    The wide proliferation of wireless services and applications with increasing bandwidth needs is rapidly creating a spectrum shortage. However, the problem is caused primarily by inefficient legacy spectrum allocation policies, so that even when some applications suffer from lack of bandwidth, there is idle capacity in other bands. To deal with this challenge, the FCC, ITU and other regulatory orga... View full abstract»

    In a typical digital filter or digital signal processing class, students are asked to design a digital filter of a specified type and fixed order. The design may or may not be satisfactory for any application but almost always in industry, the best design is required that would satisfy certain desired specifications which are usually predefined on the basis of system considerations. Unfortunately,... View full abstract»

    This paper reports the transistor-level design of a 130-nm CMOS continuous-time cascade SigmaDeltamodulator. The modulator topology, directly synthesized in the continuous-time domain, consists of a third-order stage followed by a second-order stage, both realized using Gm-C integrators and a 4-bit internal quantizer. Dynamic element matching is included to compensate for the non-linearity of the ... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (722 KB) | HTML iconHTML

    This paper proposes a multiplexing scheme to realize an I/Q channel time-interleaved (TI) band-pass sigma-delta modulator (BPSDM) that shares OTAs to minimize power consumption and silicon area for a low-IF wireless receiver. The test chip was fabricated for a 10.7-MHz IF system with a 0.35-mum CMOS process. The measured peak SNDR for a 200-kHz bandwidth is approximately 73 dB. The power consumpti... View full abstract»

    In this paper an exact state equivalency including the input signal between continuous-time (CT) ΣΔ modulators and their discrete-time (DT) counterparts is derived. The equivalency is then generalized to include the very important non-ideal effect of excess loop-delay, that plays a crucial role in continuous-time modulators. With this new state-space equivalency, an efficient tool ... View full abstract»

    Cited by:  Papers (4)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (429 KB) | HTML iconHTML

    A new architecture and signal processing methodology is proposed to implement a first-order single-bit delta-sigma (DeltaSigma) analog-to-digital converter (ADC). The proposed design converts an analog input voltage into a time-difference variable and performs the DeltaSigma signal processing in the time-mode. This offers an incredibly compact and low-power ADC solution while thriving in a low-vol... View full abstract»

    This paper presents a new low-voltage MOS-only circuit technique to implement oversampling ΣΔ modulators in purely digital CMOS technologies. The basis of the proposed design strategy is a combination of log domain processing and the MOSFET operating in subthreshold. In this sense, compact circuit implementations are given for all the required basic building blocks, such as compres... View full abstract»
