A Pseudo-Series Resonance CMOS Oscillator

A Pseudo-Series Resonance CMOS Oscillator 150 150
Author(s): Jiawen Chen, Kai Xu, Teerachot Siriburanon, Robert Bogdan Staszewski

Abstract:

This article presents a single-core, low-phase-noise (PN) digitally controlled oscillator (DCO) employing a pseudo-series resonance (pseudo-SR) technique with a transformer-based resonator. The proposed pseudo-SR resonator offers two key advantages: 1) a low impedance with a 180° phase shift at the impedance pole, emulating series resonance (SR) to enable single-stage oscillation and reduce …

0.13 K NETD D-Band CMOS Passive Imager With Noise Suppression Analysis

0.13 K NETD D-Band CMOS Passive Imager With Noise Suppression Analysis 150 150
Author(s): Zahra Mohseni, Sajjad Sabbaghi, Hai Yu, Peixin Han, Yuhao Yuan, Qun Jane Gu

Abstract:

This article presents a new system design and in-depth analysis of a wideband, low-power passive imaging receiver based on a Dicke-switch architecture, implemented in 28 nm CMOS technology. The proposed structure employs a three-coil gm-boosting technique for the low-noise amplifier (LNA). This approach reduces the LNA’s noise figure (NF) and …

A 9-GHz Low-In-Band Noise Sub-Sampling-Chopper PLL With Charge-Share Canceling Technique

A 9-GHz Low-In-Band Noise Sub-Sampling-Chopper PLL With Charge-Share Canceling Technique 150 150
Author(s): Xiangjian Kong, Kai Xu, Huanlin Xie, Mingchao Jian, Hao Lian, Robert Bogdan Staszewski, Chunbing Guo

Abstract:

This article presents a low-jitter sub-sampling chopper phase-locked loop (SS-CPLL) that incorporates a novel chopping charge pump (C-CP) to mitigate 1/f noise in short-channel devices operating at a low supply voltage of 0.75 V. A charge-share cancellation technique is introduced to suppress ripple generated by residual charge from the previous reference …
