A novel general-purpose theorem for the analysis of linear circuits
(Institute of Electrical and Electronics Engineers (IEEE), 2021-01-01)
Article
Open AccessA novel general-purpose theorem for the analysis of linear circuits is stated and proven in this brief. When applying the proposed theorem, any current (voltage) of interest is determined by finding first an equivalent ... -
A closed-loop capacitance-to-frequency converter for single-element and differential capacitive sensors
(2020-11-01)
Article
Restricted access - publisher's policyA novel closed-loop switched-capacitor(SC) capacitance-to-frequency converter (CFC) is presentedin this paper. The proposed CFC is capable of measuring from either a single-element or a differential capacitive sensor, ... -
LED-Based Wake-Up circuit for microcontrollers
(2020-07-15)
Article
Open AccessThis article proposes, analyzes, and tests a wake-up circuit for a microcontroller (MCU) that uses a light-emitting diode (LED), operating as a photodetector, illuminated by a smartphone flashlight. The wake-up circuit ... -
Demodulating AM square signals via a digital timer for sensor applications
(2020-05-01)
Article
Restricted access - publisher's policyThis paper evaluates theoretically and experimentally the performance of a timer-based demodulator applied to low-frequency amplitude-modulated (AM) square signals coming from sensor circuits. The demodulator extracts the ... -
Toward non-CPU activity in low-power MCU-Based measurement systems
(2020-01-01)
Article
Open AccessThis article evaluates the benefits of having peripheral-triggered peripherals in a microcontroller unit (MCU) intended for low-power sensor applications. In such an architecture, the functionality is moved from the central ... -
Analysis of the optimum gain of a high-pass l-matching network for rectennas
(MDPI AG, 2017-07-25)
Article
Open AccessRectennas, which mainly consist of an antenna, matching network, and rectifier, are used to harvest radiofrequency energy in order to power tiny sensor nodes, e.g., the nodes of the Internet of Things. This paper demonstrates ... -
Thermal phase lag heterodyne infrared imaging for current tracking in radio frequency integrated circuits
(2017-02-27)
Article
Open AccessWith thermal phase lag measurements, current paths are tracked in a Class A radio frequency (RF) power amplifier at 2 GHz. The amplifier is heterodynally driven at 440 MHz and 2 GHz, and its resulting thermal field was ... -
Optimal inductor current in boost DC/DC converters operating in burst mode under light-load conditions
(2016-01-01)
Article
Open AccessThis letter analyzes how the efficiency of boost dc/dc converters operating in burst mode under light-load conditions can be improved by an appropriate selection of the inductor current that transfers energy from the input ... -
MOSFET dynamic thermal sensor for IC testing applications
(2016-05-01)
Article
Open AccessThis paper analyses how a single metal-oxide-semiconductor field-effect transistor (MOSFET) can be employed as a thermal sensor to measure on-chip dynamic thermal signals caused by a power-dissipating circuit under test ... -
