A 0.01 mm²10MHz RC Frequency Reference with a 1-Point On-Chip-Trimmed Inaccuracy of ±0.28% from -45°C to 125°C in 0.18μm CMOS

CMOS frequency references based on RC oscillators are usually preferred over bulky crystals in loT applications [1-5]. However, due to the process spread and finite temperature coefficient (TC) of most on-chip resistors, RC oscillators require trimming and temperature compensation to achieve decent accuracy. Enabled by high-resolution...

Transverse-EPT: A local first order electrical properties tomography approach not requiring estimation of the incident fields

A new local method for magnetic resonance electrical properties tomography (EPT), dubbed transverse-EPT (T-EPT), is introduced. This approach iteratively optimizes the dielectric properties (conductivity and permittivity) and the z-component of the electric field strength, exploiting the locally E-polarized field structure typically present...

Medium access control and network layer design for 60 GHz wireless personal area networks

The unlicensed frequency band around 60 GHz is a very promising spectrum due to its potential to provide multiple gigabits per second based data rates for short range wireless communication. Hence, 60 GHz radio is an attractive candidate to enable ultra high rate Wireless Personal Area Networks (WPANs), which are expected to support wireless...
