A 1-8 GHz, 190MHz BB BW Mixer-First Receiver With Bootstrapped Mixer Switches Achieving Over 16dBm In-Band IIP3

A 1-8 GHz, 190MHz BB BW Mixer-First Receiver With Bootstrapped Mixer Switches Achieving Over 16dBm In-Band IIP3 150 150
Author(s): Erwin Hardeveld, Ronan van der Zee, Bram Nauta

Abstract:

In this article, we propose a wideband mixer-first receiver with improved in-band (IB) linearity. It uses bootstrapped N-path mixer switches to achieve a constant on-state gate–source voltage for large IB signals. We analyze the tradeoff between on-state resistance and off-state subthreshold current in conventional mixer switches and introduce a …

A 180-nm Voltage-Controlled Magneto-Electric RAM With Sub-1-ns Switching Time

A 180-nm Voltage-Controlled Magneto-Electric RAM With Sub-1-ns Switching Time 150 150
Author(s): Haris Suhail, Haoran He, Vinod Kurian Jacob, Jiyue Yang, Kang L. Wang, Sudhakar Pamarti

Abstract:

Memory performance has emerged as a critical factor influencing both system speed and energy efficiency. However, conventional memory technologies such as embedded Flash (eFlash) and static RAM (SRAM) encounter significant scalability limitations beyond the 28-nm CMOS node. Among novel emerging memory technologies, spin-transfer-torque magnetic RAM (STT-MRAM) has gained prominence due …

An 8.5 MHz 42 ppm/°C Relaxation Oscillator With Charge-Pump Delay Cancellation and Digital Chopping Demodulation

An 8.5 MHz 42 ppm/°C Relaxation Oscillator With Charge-Pump Delay Cancellation and Digital Chopping Demodulation 150 150
Author(s): Yongjia Li, Jianlin Xia, Feng Cheng, Yifan Cao, Jin Wu, Encheng Zhu, Xiaofeng Sun, Dejin Wang, Long Zhang, Zhongyuan Fang, Weifeng Sun

Abstract:

This letter presents an RC oscillator featuring a mixed-signal compensation loop that simultaneously mitigates comparator offset, loop delay, switch on-resistance, and temperature dependency. The oscillator employs an auxiliary comparator, a charge pump, and a differential difference amplifier (DDA)-based main comparator to suppress ramping voltage overshoots caused by device and …

CORDIC-Less Digital Polar Transmitter Architecture Based on Delta-Sigma Modulator

CORDIC-Less Digital Polar Transmitter Architecture Based on Delta-Sigma Modulator 150 150
Author(s): Yuncheng Zhang, Zezheng Liu, Duo Li, Minzhe Tang, Yi Zhang, Hóngyè Huáng, Dingxin Xu, Waleed Madany, Ashbir Aviat Fadila, Wenqian Wang, Yuang Xiong, Daxu Zhang, Garry Pranata Kusuma, Hiroyuki Sakai, Kazuaki Kunihiro, Atsushi Shirane, Kenichi Okada

Abstract:

Conventional digital polar transmitters (TXs) suffer from limited power efficiency and linearity due to the multi-bit nature of intermediate signals. This work proposes a digital polar TX architecture that avoids such drawbacks by reducing the bit count of TX signals. The proposed TX oversamples and quantizes multi-bit I/Q inputs …

A Zero-Voltage Switching Buck Converter With Enhanced Efficiency Over a Wide Load Range

A Zero-Voltage Switching Buck Converter With Enhanced Efficiency Over a Wide Load Range 150 150
Author(s): Jingyi Yuan, Qingqing Min, Siyang Liu, Lin Cheng

Abstract:

This article presents a wide-input-range buck converter featuring a conduction-loss-minimized zero-voltage switching (ZVS) technique. The proposed ZVS topology enables accurate ZVS operation across a wide range of input voltage ( $V_{\mathrm {IN}}$ ) and load current ( $I_{\mathrm {O}}$ ). By keeping the auxiliary inductor current pulse in the ZVS branch separate …
