The motion of a continuously operating reference station is usually dominated by the long-term crustal motions of the tectonic block on which the station is located. Monitoring changes in the coordinates of reference stations located at tectonic plate bo...

In this paper, we present a 0.3 V body-driven operational transconductance amplifier (OTA) that exploits a biasing approach based on the use of a replica loop with gain. An auxiliary amplifier is exploited both in the current mirror load of the first sta...

A closed-form solution for the common and differential modal currents induced on a pair of infinitely long parallel conductors by a source, field coupled to a power line, is derived. For lossy conductors, the current consists of a continuous spectrum of ...
