A single-chip multimode multiband receiver is designed and implemented in a 90-nm CMOS process for fourth-generation mobile platforms. The receiver includes nine primary low-noise amplifier (LNA) and five secondary LNA input ports, and supports long-

In this paper, we present a multibit continuous-time delta-sigma modulator based on a 5-bit successive approximation quantizer. The use of successive approximation, instead of flash, is driven by the desire to reduce the quantizer power and area. The

This paper explores the use of finite-impulse response (FIR) filters in the feedback path of a low-pass sigma-delta modulator in order to combat some nonideal effects encountered in an analog implementation. In this approach, the filter corresponding

The clock jitter effect in continuous-time data converters is studied. Using the state-space approach, closed-form formulas predicting precisely the spectra of jitter-induced noise are derived. The results are quite general and applicable to all type

Fourth-generation mobile devices use wide channel bandwidths and OFDM modulation to achieve high data rates. In particular, OFDM modulation in LTE20 creates up to 100 Resource Blocks (RB) each containing 12 subcarriers with 15kHz spacing, spread over

A third-order continuous-time delta-sigma modulator achieving 76dB dynamic range over 5MHz signal bandwidth is presented. The modulator has a monotonic lowpass signal transfer function and achieves over 70dB anti-aliasing. The prototype chip implemen

CT Delta-Sigma modulators provide a solution for low-power analog to digital conversion with built in anti-aliasing but they are sensitive to clock jitter. One way of mitigating the jitter problem is to use a multi-bit quantizer with increased number

Incremental data converters (IDC) can achieve absolute accuracies higher than 16 bits with very low power consumption. However, single-bit IDCs require numerous clock cycles per conversion. In this paper, the advantages of employing multibit quantize

We present a general methodology for the design of continuous-time sigma-delta modulators with a lowpass signal transfer function without peaking. We also propose two new feedforward architectures exhibiting significantly lower sensitivity to coeffic
