摘要： A new type of amplifier, herein designated a resource pooling amplifier, involves extended usage of one or more inductors that is implemented by sharing. The sharing is either by switching the inductor or inductors among more than one load terminal at the same time (e.g., a bridged configuration or two different loads terminals with different polarity requirements) or by using the inductor or inductors for more than one purpose at different times. The inductor or inductors may be time shared such as by allocating different phases of a clock. The inductor or inductors may also be shared by monitoring load requirements and using the inductor or inductors only when needed (leaving other inductor cycles for other loads). In addition, inductor sharing may be implemented during different application requirements such as if two or more loads are not needed at the same time in a system. These types of sharing may be combined.

摘要： A resistor-input transconductor includes a circuit configured to generate a common-mode compensation current. The common-mode compensation current is used to compensate for the common-mode voltage of the inputs. A current output of the resistor-input transconductor is proportional to a voltage difference between the two inputs and essentially independent of a common-mode voltage of the two inputs. The resistor input transconductor may be applied in a variety of applications including, for example, communications.

摘要： The invention relates to a system and a method for compensating the temperature of a resistor (1). A resistor (1) which can be controlled with respect to its resistance is compared with a reference resistor (2) which is configured as a switched capacitor. A comparator (3) compares the two resistance values with each other. The comparator (3) controls the controlled resistor (1) depending on an error signal. The invention provides a temperature-stable resistor, the underlying principle being preferably suitable for transimpedance amplifiers.

摘要： An operational amplifier arrangement includes besides the two-stage operational amplifier, a third stage for tracking and holding the input offset of the first stage during an offset compensation phase which regularly interrupts the normal operation of the arrangement. To this purpose four switches are clocked, whereby the first stage is decoupled from the second stage during an offset compensation phase, whereby the feedback loop of the third stage is interrupted during normal mode, and whereby during the offset compensation phase the input is decoupled from the arrangement, while both input terminals are shorted. A Miller capacitor across the second stage prevents the output from drifting during the offset compensation mode.

摘要： Methods and systems are described for cancelling interference in a microphone system. A positive bias voltage is applied to a first microphone diaphragm and a negative bias voltage is applied to a second microphone diaphragm. The diaphragms are configured to exhibit substantially the same mechanical deflection in response to acoustic pressures received by the microphone system. A differential output signal is produced by combining a positively-biased output signal from the first microphone diaphragm and a negatively-biased output signal from the second microphone diaphragm. This combining cancels common-mode interferences that are exhibited in both the positively-biased output signal and the negatively-biased output signal.

摘要： A dual compensation operational amplifier is suitable for use in an environment that experiences fluctuations in ambient energy levels. A dual compensation impedance can be determined to nullify or compensate for effects of an input offset voltage or an input bias current or both. Adjustments to the dual compensation impedance can be made based on calibration data for various environmental conditions so that the dual compensation impedance can be either pre-set for anticipated conditions in different target operational environments, or automatically adjusted in-situ. Target operational environments that may benefit from such a dual compensation impedance include remote areas that experience extreme or variable temperatures, high altitudes, space, or high radiation environments.

摘要： A voltage sensing circuit (400) includes a voltage to current converter (112), an integrator (442 ), a sample and hold amplifier (156), and a modulator. The voltage to current converter produces a modulated current corresponding to an input voltage. The integrator demodulates the modulated current and produces a voltage sum of the demodulated current. The sample and hold amplifier samples the voltage sum and provides an output voltage corresponding to the voltage sum. The modulator modulates the output voltage and provides the modulated voltage to the voltage to current converter as a feedback voltage.
