A 12-bit 1-GS/s Current-Steering DAC With Paired Current Source Switching Background Mismatch Calibration 150 150
Author(s): Chang-Un Park, Jae-Hyun Chung, Chunsuk Kim, Hyun-Woo Shin, Charlie Tahar, Seung-Tak Ryu

Abstract:

This article presents a spur-suppressed background calibration technique for high-speed current-steering digital-to-analog converters (DACs), based on a paired current source (CS) switching scheme. In conventional background calibration, periodic switching of CSs to and from the calibration mode introduces unwanted glitches that appear as spurious tones. The proposed technique introduces an …

A Broadband and Compact GaN Millimeter-Wave MMIC SPDT Switch Using Modified π-Networks

A Broadband and Compact GaN Millimeter-Wave MMIC SPDT Switch Using Modified π-Networks 150 150
Author(s): Chaorong Wang, Quan Pan, Xiaohu Fang

Abstract:

This letter presents a design methodology for broadband and compact millimeter-wave (mm-wave) single-pole double-throw (SPDT) switches targeting the Ku–Ka band. Conventional SPDT switches based on quarter-wavelength transmission line typically occupy significant chip area, while alternative designs utilizing standard $\pi $ -type equivalent circuits often suffer from bandwidth degradation due to …

Abstract:

Foldable mobile applications recently have been leading the battery charger to have a slim height with a small form-factor and high efficiency at higher input voltages to increase the power density. Another trend for mobile applications is the power sharing, which enables to supply two mobile devices simultaneously. To meet …

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 …

Polar-Axis Orientation Fluctuations and the Impact on the Intrinsic Variability in Ferroelectric Capacitors

Polar-Axis Orientation Fluctuations and the Impact on the Intrinsic Variability in Ferroelectric Capacitors 150 150
Author(s): Wei Zhang, Jianze Wang, Xuanyao Fong

Abstract:

We utilized phase-field simulations to investigate the effects of polar-axis (PA) orientation fluctuations on the extrinsic properties of single ferroelectric (FE) grains, focusing on the coercive electrical field (EC) and the remnant polarization (Pr). The underlying mechanisms through which PA orientation fluctuations influence polarization behavior are studied to gain insights …
