Transmit digital-to-analog converters have become an essential building block for state-of-the-art Ethernet infrastructures. They are also one of the most significant sources of power consumption in an Ethernet physical layer (PHY) transceiver. These devices must maintain high linearity and a well-defined impedance of 100 Ω while operating at a...

This paper presents a continuous-Time zoom ADC for audio applications. It combines a 4-bit noise-shaping coarse SAR ADC and a fine delta-sigma modulator with a tail-resistor linearized OTA for improved linearity, energy efficiency, and handling of out-of-band interferers compared to previous designs. In 160 nm CMOS, the prototype chip...

In this paper, we propose a discrete-time IIR low-pass filter that achieves a high-order of filtering through a charge-sharing rotation. Its sampling rate is then multiplied through pipelining. The first stage of the filter can operate in either a voltage-sampling or charge-sampling mode. It uses switches, capacitors and a simple gm-cell, rather...

In the last couple of years, mobile telephony has truly become global, with more than 4 billion users worldwide nowadays (compared to less than 1bn ten years ago). This has represented a boost not just for the mobile phones industry, but also for that of wireless infrastructure. Larger-scale production and increased competition have transformed...

As the first stage of the amplifier chain aiming for the base station applications, a highly linear low noise amplifier (LNA) dictates very high performance for optimum coverage with a best signal quality. In today’s commercial market, the GaAs enhancement-mode pHEMT based LNA is dominant. However, a SiGe-based LNA, due to its high integration,...
