Settling behavior of the binary-weighted switched-capacitor digital-to-analog converter output is analyzed and a design method for fast settling is presented. A calibration circuit that effectively reduces settling time beyond the process limit is also proposed and verified with various simulations.

The current-output fluxgate may be tuned by using a serial capacitor. Such tuning increases the sensor sensitivity in the situation when the pick-up coil has low number of turns. We achieved a signal/feedthrough ratio improvement by a factor of 5. The measured parameters fit the simplified theoretical model within 20% deviation

A novel current-mode first-order all-pass filter with low input and high output impedance feature is presented. The circuit realization employs a single dual-X-second-generation current conveyor, one grounded capacitor, and one grounded resistor, which is a minimum component realization. The theoretical results are verified using PSPICE simulation program with TSMC 0.35 μm CMOS process parameters.

There is an ever-growing interest within the fields of neurophysiology—as well as within coding theory and signal processing—into the particular information transmission method employed by most neurons: spikes. Many models used today regard those voltage pulses as uniform events where only the occurrence of an event from a particular neuron at a particular moment in time matters. This signal re...

Double-sided Inductor–Capacitor–Capacitor (LCC) or hybrid compensation network is often used in the traditional methods to realize load-independent output wireless power transfer; however, these require changes of operating frequency network, and adoption more switches components, resulting reduction reliability system. In this article, a single switch topology using switched capacitor was prop...

This paper presents a CMOS temperature sensor based on the thermal dependencies of the leakage currents targeting the 65 nm node. To compensate for the effect of process fluctuations, the proposed sensor realizes the ratio of two measures of the time it takes a capacitor to discharge through a transistor in the subthreshold regime. Furthermore, a novel charging mechanism for the capacitor is pr...

This paper introduces a merged converter topology for supplying high-brightness light-emitting diodes for lighting applications. The converter combines a boost-based power factor correction rectifier (PFC) and a resonant converter in a single-stage. In this topology both converters share the same switching components and a bulky electrolytic capacitor, existing in conventional systems, is repla...

Characterization was performed on 60 nm +/3 nm films of atomic layer deposition (ALD) hafnium dioxide (HfO2) and aluminum oxide (Al2O3), and plasma-enhanced chemical vapor deposition (PECVD) silicon nitride (Si3N4) as MIM capacitor dielectric for GaAs HBT technology. The capacitance density of MIM capacitor with ALD HfO2 (2.73 fF/m 2 ) and Al2O3 (1.55 fF/m 2 ) is significantly higher than tha...

In the low voltage based renewable systems like PV and Fuel cell applications, step-up of output to drive loads is essential. For this, integration switched-capacitor (SC) units with dc-ac converters will have potential advantages improved efficiency, optimal switching devices, small size passive elements (L C) as compared traditional two-stage conversion system (dc/dc converter dc/ac converter...
