There are three different loop detectors used to detect present and absent vehicles.’ One of them is known as self-tuning detector. This type of detector utilizes both pavement loops as part of a parallel resonant tank circuit and a closed-loop feedback circuit. It automatically adjusts a voltage-tuned oscillator to a predetermined frequency relative to the resonant frequency of the tank.’ A ch...

A microelectromechanical systems (MEMS) temperature sensor based on a cascade three-stage “bent-beam” structure is described in this paper. A suspended structure mechanically deforms in response to the change in ambient temperature, and then, a displacement is obtained; the structure is composed of three cascaded systems in order to enhance sensor sensitivity. The final conversion is made to an...

In this method to obtain the rotor position of switched reluctance motor by means of resonant circuit method. The resonant circuit comprising of the motor and the power electronic converter, motor phase inductance and the parasitic capacitance of converter switches. F...

We show that flux qubits can be efficiently entangled by inductive coupling to a tunable resonant circuit, in the scheme reminiscent of atoms’ entanglement through the optical cavity mode. It is shown, in particular, that the singlephoton excitation of the resonator produces the pure Bell state of qubits with the completely disentangled LC circuit. 03.67.Lx; 85.25.Cp; 03.65.Ud Typeset using REVTEX

This series of articles discusses oscillator phase noise reduction techniques and gives specific resonant circuit solutions using lumped and distributed parameters for both frequency stabilization and phase noise reduction. These topics are covered in Part 1. Phase noise improvement can also be achieved by appropriate low-frequency loading and feedback circuitry optimization. The feedback syste...

This paper presents a resonant-based read-out circuit for capacitive pressure sensors. The proposed read-out circuit consists of an LC oscillator and a counter. The circuit detects the capacitance changes of a capacitive pressure sensor by means of frequency shifts from its nominal operation frequency. The proposed circuit is designed in 0.18μm CMOS with an estimated power consumption of 43.1mW...
