Granted: 2000-05-30
Abstract: A small variable capacitor which provides a large electrostatic capacity, whose variability of the electrostatic capacity is large, and has an excellent electrical strength and a high Q value which indicates an index of performance of the capacitor, even though it is a single element, is provided. One end of a movable section composing a movable electrode is supported by a supporting section. A driving electrode and a detecting electrode are provided facing to the movable electrode. When an external bias voltage is applied between the movable electrode and the driving electrode, Coulomb force is generated between them. Due to that, the movable section is attracted toward the driving electrode while keeping a balance between its own resilience (stability) and the Coulomb force. At this time, part of the movable section facing to the detecting element is displaced more than the other part of the movable section facing to the driving electrode. That is, an average distance between the movable section and the detecting electrode becomes narrower as compared to an average distance between the movable section and the driving electrode. Thereby, because an electrostatic capacity between the movable section and the detecting electrode is inversely proportional to the average distance, a large electrostatic capacity may be obtained and a variability of the electrostatic capacity becomes large.

IPC: H01Q21/00
Filed: 1997-04-29
Granted: 1999-11-23
Abstract: A process for collecting phase and amplitude calibration data for an active array system without the use of external sensors.   The relative phase and amplitudes of adjacent T/R modules are determined when viewed through the entire array system.   The calibration process  involves collecting and storing these phases and amplitudes for future use.  A pulse-to-pulse phase or amplitude modulation mode is employed.  An element is commanded into this mode to  separate  its  signal  (in  frequency)  from  competing signals and leakages from the surrounding modules.  A T/R inversion  command  allows  far a  single  element  to  be switched to a transmit state while the remainder of the array is in the receive state.  This provides for a reference signal during receive calibration, and for single module testing during transmit calibration.

Title: Method for multilevel dram sensing
Inventor: BIRK GERSHOM
IPC: G11C11/4091
Filed: 1997-09-30
Granted: 2005-04-12
Abstract: A method for performing a sense and restore operation in a multilevel DRAM is described. The method describes the selective enabling of the sense amplifiers to operate at predetermined sensing thresholds. The multilevel DRAM stores two bits per cell using a four-voltage-level-per-cell system. Folded bitlines are divided into sub- bitlines each having dedicated sense amplifiers. The sense amplifiers are selectively enabled to operate at predetermined sensing thresholds to thereby greatly simplify the sense and restore operations. The circuit has standard CMOS bitline sense amplifier transistors connected thereto with pull down transistors that may be selectively enabled by switch signals. The length and width of these pull down transistors are varied to thereby effect the switching threshold of the sense amplifier.
