GaN Power Switch for Power Distribution Protection
GaN Power Switch for Power Distribution Protection 150 150
Author(s): Ronald Hassib Galvis Chacón, José Alexandre Diniz, Saulo Finco

Abstract:

The electrical power system (EPS) of satellites requires protection devices to isolate failures in short-circuit conditions that can occur in payloads due to various sources, such as debris, mishandling, or radiation. Latching current limiter (LCL) implemented with a pMOS power transistor is typically used for this task. Radiation can also …

A Fully Integrated Digital LDO With Adaptive Sampling and Statistical Comparator Selection
A Fully Integrated Digital LDO With Adaptive Sampling and Statistical Comparator Selection 150 150
Author(s): Shun Yamaguchi, Takashi Hisakado, Osami Wada, Mahfuzul Islam

Abstract:

Digital LDOs are gaining attention for their operation with small output capacitance. Adaptive sampling with a large frequency scaling ratio is required for fast transient response with low-power operation. Furthermore, the design of a fluctuation detector to deal with large load steps is important. This letter describes an adaptive-sampling digital …

A 23.9-μW 13.6-Bit Period Modulation-Based Capacitance-to-Digital Converter With Dynamic Current Mirror Front-End
A 23.9-μW 13.6-Bit Period Modulation-Based Capacitance-to-Digital Converter With Dynamic Current Mirror Front-End 150 150
Author(s): Hyeyeon Lee, Donguk Seo, Young-Jin Woo, Yoonmyung Lee, Inhee Lee, Youngcheol Chae

Abstract:

This letter proposes a low-power high-precision capacitance-to-digital converter (CDC) utilizing a dynamic current mirror (DCM) to transform a sensor input capacitance $(C_{\mathrm{ IN}})$ into an output current. The resulting current is directly proportional to the ratio of $C_{\mathrm{ IN}}$ to an internal reference capacitor $(C_{\mathrm {REF}})$ and …

A 50–67-GHz Transformer-Based Six-Port Balanced-to-Unbalanced Quadrature Hybrid Coupler
A 50–67-GHz Transformer-Based Six-Port Balanced-to-Unbalanced Quadrature Hybrid Coupler 150 150
Author(s): Yang Gao, Howard C. Luong

Abstract:

This letter presents the first on-chip transformer-based six-port balanced-to-unbalanced quadrature hybrid coupler (QHBC). The proposed six-port QHBC employs three transformers to replace eight inductors design in conventional LC-based couplers for miniaturization. Fabricated in CMOS 28 nm, the overall size of the proposed coupler is 0.23 mm $\times0.17$ mm, which is equivalent to $0.046\…
