SET Analysis and Radiation Hardening Approaches for Different LNA Topologies

Title: SET Analysis and Radiation Hardening Approaches for Different LNA Topologies

Conference name: Workshop on Compound Semiconductor Devices and Integrated Circuits 2017 (WOCSDICE 2017)

Abstract: This paper analyses the effects of single-event transients (SETs) on CMOS low noise amplifiers (LNA) designed for a 0.18 mm technology. Two well-known topologies, the common-source and common-gate cascodes, have been analysed when heavy ions strike the most sensitive nodes of these structures. In order to simulate these strikes both a physics-based technology computer aided design (TCAD) tool and an electrical circuit domain simulator have been used. This way the physics information given by the TCAD tool is combined with the fast transient simulations performed in circuit simulators. To study their SET performance, the maximum voltage peak and the recovery time of the output signal were calculated for both LNAs. Additionally, a safe operating area can be defined, setting the boundaries for acceptable SETs. Radiation hardening by design techniques have been applied at the most vulnerable nodes of both LNAs. The proposed mitigation approaches make both LNAs hardened against radiation, considerably improving their SET performance.

Area Efficient Dual-Fed CMOS Distributed Power Amplifier

Title: Area Efficient Dual-Fed CMOS Distributed Power Amplifier
Authors: Javier del Pino, Sunil L. Khemchandani, Sergio Mateos-Angulo, Daniel Mayor-Duarte and Mario San-Miguel-Montesdeoca
Journal name: Electronics

Abstract: In this paper, an area-efficient 4-stage dual-fed distributed power amplifier (DPA) implemented in a 0.35 µm Complementary Metal Oxide Semiconductor (CMOS) process is presented. To effectively reduce the area of the circuit, techniques such as using multilevel inductors and closely-placing conventional spiral inductors are employed. Additionally, a novel technique based on stacking inductors one on top of others is implemented. Based on these techniques, a 32% area reduction is achieved compared to a conventional design without a noticeable performance degradation. This reduction could be further exploited as the number of stages of the dual-fed DPA increases.

A System for Controlling and Monitoring IoT Applications

Title: A System for Controlling and Monitoring IoT Applications
Authors: Zebenzui Lima, Hugo García-Vázquez, Raúl Rodríguez, Sunil L. Khemchandani, Fortunato Dualibe, Javier del Pino
Journal name: Applied System Innovation (ISSN 2571-5577). Special Issue «Applications of Advanced Sensors on Applied System Innovation of IoT (Internet of Things)»

Abstract: In this work, the design and implementation of an open source software and hardware system for Internet of Things (IoT) applications are presented. This system permits the remote monitoring of supplied data from sensors and webcams and the control of different devices such as actuators, servomotors and LEDs. The parameters which have been monitored are brightness, temperature and relative humidity all of which constitute possible environmental factors. The control and monitoring of the installation is realised through a server which is managed by an administrator. The device which rules the installation is a Raspberry Pi, a small and powerful micro-computer in a single board with low consumption, low cost and reconfigurability.

Single event transients mitigation techniques for CMOS integrated VCOs

Title: Single event transients mitigation techniques for CMOS integrated VCOs
Authors: D. González-Ramírez, S. L. Khemchandani⁠, J. del Pino, D. Mayor-Duarte, M. San-Miguel-Montesdeoca, S. Mateos-Angulo
Journal name: Microelectronics Journal

Abstract: Single event transients (SETs) in analog integrated circuits result from the interaction of a heavy ion or high-energy proton with a sensitive p-n junction. SETs induce electron-hole pairs that can lead to current spikes, which propagate through the integrated circuit and can result in substantial transient peaks at the output voltage. This paper proposes techniques to mitigate SETs in CMOS voltage controlled oscillators (VCOs) without affecting circuit specifications. A VCO was designed to meet the IEEE 802.15.4 specifications. First, the weakest nodes were detected, and then particle strikes with a LET ranging from 14.47 to 57.86 MeV cm2 mg−1 were applied at these nodes. Amplitude variation, recovery time and phase shift were obtained at the output nodes. RHBD techniques are discussed and applied to redesign the VCO. The proposed mitigation techniques reduce the recovery time by approximately 59%, the output phase displacement by 74.2% and the amplitude variation by 96.7%.
