IQ offset and gain mismatch compensation for phase-domain ADC

A phase-domain analog-to-digital converter (PhADC) is a promising alternative to a pair of amplitude-domain in-phase and quadrature (IQ) ADCs for low power FSK/PSK demodulation, but due to the nonlinear amplitude-to-phase conversion, IQ offsets and gain mismatch can produce nonlinear phase distortions which that can lead to phase errors and an...

A Three-Phase Unbalanced Load Flow Solver for Large-Scale Distribution Power Systems

The calculation of power flow through electrical networks has been utilized commonly in transmission networks as the first calculation tool to assess their steady state conditions. However, the current introduction of renewable micro-sources (many of them single-phase connected) and the implementation of microgrids makes the calculation of power...

A Highly-Scalable Thermal-Diffusivity-Based Temperature Sensor

A highly digital temperature sensor, based on the thermal diffusivity of silicon, for thermal management applications has been reported. Recently, Thermal-Diffusivity based temperature sensors have undergone a radical change from an analog-based readout architecture to a more digital VCO-based one. However the more digital approach led to...
