PROBLEM TO BE SOLVED: To provide a switched capacitor amplifier which can output a stable output voltage. SOLUTION: A switched capacitor amplifier is capable of operating so as to eliminate a charge/discharge time difference between an input capacitor 18 and an output capacitor 19. Accordingly, in a shift from a hold state to a sample state, for example, even if one terminal voltage V2 of the output capacitor 19 abruptly increases to an output voltage VOUT, another terminal voltage Vs of the output capacitor 19 does not increase abruptly. In other words, an input voltage to an internal amplifier 11 does not increase abruptly. Hence, an output voltage of the internal amplifier 11 becomes stable, and therefore, the output voltage VOUT also becomes stable. COPYRIGHT: (C)2011,JPO&INPIT | ||||||

The semiconductor substrate area under a metal plate is induced to change from one type of conductivity to a different type of conductivity when a voltage in excess of the inversion threshold of the substrate is applied to the plate. A capacitor is produced which stores a charge proportional to the applied voltage between the metal plate and the induced region. The induced region is connected to an input electrode. When a voltage is applied to the input electrode the voltage on the fixed plate of the capacitor is boosted by an amount proportional to the applied voltage. When the voltage on the metal plate is reduced below the inversion threshold voltage the induced region reverts back to its original conductivity and the input electrode is isolated from the capacitor.

A system includes at least one capacitor comprising a dielectric material having a Curie temperature, each capacitor exhibiting an increased capacitance at a temperature below the Curie temperature and exhibiting a decreased capacitance at a temperature above the Curie temperature, a liquid source positioned adjacent to the capacitor and having a temperature above the Curie temperature, and means for exposing the capacitor to the liquid source for a predetermined time so the temperature of the dielectric material exceeds the Curie temperature, at which point the capacitance decreases. A voltage storage is connected to the capacitors to capture the increased voltage discharged from the capacitors. The capacitors are then removed from the liquid source and cooled. The capacitors may iteratively be recharged, exposed to the liquid source until their temperature exceeds the Curie temperature, connected to the voltage storage, removed from the liquid source, and cooled. | ||||||

An amplifier circuit comprises a measurement path with an amplifier (1) for providing an output voltage (Vout) depending on a measuring current (Ipd) with a first and a second amplifier input (11, 12), and an amplifier output (13). A return path of the amplifier circuit comprises a first filter (2), an auxiliary amplifier (3) and a second filter (4). In this case, the first filter (2) is designed to filter a DC voltage from the output voltage (Vout) and is connected to the amplifier output (13). The auxiliary amplifier (3) serves to convert an input voltage (Vfil) into an output current (Ifil) and has a first and a second auxiliary amplifier input (31, 32) and an auxiliary amplifier output (33). In this case, the first auxiliary amplifier input (31) is connected to the first filter (2). The second filter (4) is designed to filter noise from the output current (Ifil) and couples the auxiliary amplifier output (33) to the first amplifier input (11). | ||||||
20 | Passive amplifier | US13362069 | 2012-01-31 | US08653903B2 | 2014-02-18 | Kenneth J. Schlager; Jason Zehrung |
A passive amplifier for use with enhanced power supplies, signal preamplifiers and power amplifiers in communications systems particularly in mobile phones, laptop computers and other battery-powered and battery-limited devices. The passive amplifier can be used as an attachment to electric appliances or other power consuming equipment to significantly reduce the electric power requirements of such equipment. These passive amplifiers do not require an outside source of power and can be used to elevate battery power outputs and serve as either low noise signal preamplifiers or transmit power amplifiers for higher performance and extended battery life. Passive amplifier technology is either electromagnetic or dielectric in nature with component parts limited to inductive, capacitive and resistive components. Dielectric amplifier prototypes have gain values in the range of the 10 dB level so as to be useful in communications applications and power amplification. |
