摘要： To compensate for changes in temperature, a pair of bipolar transistors is connected to a voltage divider and receives a differential voltage that varies with temperature. The voltage divider includes a set of resistors placed in parallel. The set of resistors has a resistance that changes with temperature. As the resistance changes with temperature, the differential voltage provided by the voltage divider changes in proportion to a change in thermal voltage.

摘要： In an output stage of an operational amplifier, first(2,Q5) and second(Ql,Q4) transistors each provide a collector current under quiescent conditions to first (12, 14) and second (Il,I3)rrent sources. A resistor (Rl, R3) receives a portion of one the collector currents and produces a resistor voltage in response. An output transistor (Q3,Q6) provides a quiescent current having a value calculated as a function of the resistor voltage and a base-emitter voltage of the second transistor (Ql, Q4).

摘要： A thin film composition is made from silicon, an insulator such as alumina or silicon dioxide, and at least one additional material such as chromium, nickel, boron and/or carbon. These materials are combined to provide a thin film having a p of at least 0.02 Ω-cm (typically 0.02-1.0 Ω-cm), and a TCR of less than ±1000 ppm/°C (typically less than ±300 ppm/°C). A sheet resistance of at least 20 kΩ/O may also be obtained. The resulting thin film is preferably at least 200 A (20nm) thick, to reduce surface scattering conduction currents.

摘要： The present invention provides a JFET which receives an additional implant during fabrication, which extends its drain region towards its source region, and/or its source region towards its drain region. The implant reduces the magnitude of the e-field that would otherwise arise at the drain/channel (and/or source/channel) junction for a given drain and/or source voltage, thereby reducing the severity of the gate current and breakdown problems associated with the e- field. The JFET’ s gate layer is preferably sized to have a width which provides respective gaps between the gate, layer' s lateral boundaries and the drain and/or source regions for each implant, with each implant implanted in a respective gap.

摘要： Amplifiers with voltage and current feedback error correction are provided. In one embodiment, an amplifier includes a first input terminal, a second input terminal, an output terminal, a first stage, and a voltage feedback amplification circuit. The first stage can be used to generate first and second output currents, which can be used to control a voltage level of the output terminal. The first and second output currents can change in response to a current feedback signal and a differential input signal received between the first and second input terminals. The first stage can also generate a voltage feedback signal, which can be used by the voltage feedback amplification circuit to control a voltage level of the second input terminal based on a voltage level of the first input terminal.
