Well-known magnetometers and magnetic field sensors employing semiconductor materials are usually either not compatible with standard integrated circuit (IC) fabrication techniques, or are not sufficiently sensitive for practical usage. Currently, in order to obtain the required sensitivity, materia.....

Conventionally, frequency tuning is achieved by changing the capacitance of a tank using varactor. However, it is more power efficient to minimize the capacitance of the tank and adjust the inductance for frequency variation. Therefore, the need for a variable inductor arises.A novel integrated vari.....

The invented double-balanced quadrature-input quadrature-output divider (QIQOD) is based on conventional multiplier-based regenerative dividers but employs four different feedback loops with appropriate phase shifts. By making use of quadrature phase outputs from any quadrature signal generator, the.....

Programmed cell death is a very important cellular process that is critically involved in many diseases. A key step in the programmed cell death is the activation of a series of intracellular proteases, such as caspase-3. The invention is a novel method of detecting the early stage of programmed cel.....
