摘要： A circuit method includes periodically increasing a tail current of a differential stage of a comparator to periodically power on the differential stage to a power-on state, and periodically decreasing the tail current of the differential stage to periodically power down the differential stage to a low-power state. The periodically increasing of the tail current and the periodically decreasing of the tail current are asynchronous operations for powering on the differential stage to the power-on state and powering down the differential stage to the low-power state. Periodically increasing the tail current and the periodically decreasing the tail current asynchronously for powering on the differential stage to the power-on state and powering down the differential stage to the low-power state provide for low noise and high speed during signal comparison.

摘要： A data acquisition system (200) includes a programmable gain amplifier (202), an analog-to-digital converter (204), a filter (206), and control circuitry. The programmable gain amplifier (202) is operatively connected to receive an analog input signal on its input (208, 210) and generates an amplified signal on its output (212, 214) in accordance with gain control signals (gc1-gc3). The analog-to-digital converter (204) is operatively connected to receive the amplified signal from the amplifier (202) and generates a digitized signal on its output (216, 218). The filter (206) is operatively connected to receive the digitized signal from the converter (204) and generates a filtered digital signal on its output (220, 222). The control circuitry is operatively connected to the amplifier (202) and to the converter (204) and is also responsive to the gain control signals (gc1-gc3) for dynamically adjusting power between the amplifier and converter when the gain control signals (gc1-gc3) are changed.

摘要： The invention relates to analogue integrated electronic circuits using differential pairs (T1, T2). An automatic method of correcting offset voltage is proposed, comprising the following steps: short-circuiting the inputs (V1, V2) of the differential circuit during a calibration phase that is distinct from the normal usage phase; charging a capacitance through the difference in the output currents of the branches of the differential pair in this phase; comparing the voltage across the terminals of the capacitance with at least one threshold; retaining in memory, during the normal usage phase following the calibration phase, the result of the comparison; applying, in the normal usage phase, a correction dependent on the result retained in memory to a current source (SC1, SC2) of a follower stage upstream of the differential pair.

摘要： Current-controlled CMOS (C3MOS) fully differential integrated wideband amplifier/equalizer with adjustable gain and frequency response without additional power or loading. A novel approach is presented by which adjustable amplification and equalizer may be achieved using a C3MOS wideband data stage. This may be referred to as a C3MOS wideband data amplifier/equalizer circuit. This employs a wideband differential transistor pair that is fed using two separate transistor current sources. A switchable RC network is communicatively coupled between the sources of the individual transistors of the wideband differential transistor pair. There are a variety of means by which the switchable RC network may be implemented, including using a plurality of components (e.g., capacitors and resistors connected in parallel). In such an embodiment, each component may have an individual switch to govem its connectivity in the switchable RC network thereby allowing a broad range of amplification and equalization to be performed.

摘要： A variable gain amplifier circuit is provided so that an electric current decreases when a voltage gain is lowered and that the amplifier circuit is substantially free of a deterioration in distortion characteristics.
The bases of bipolar transistors Q1, Q3 and Q5 and the bases of bipolar transistors Q2, Q4 and Q6 are connected in common with each other, these bipolar transistors forming a plurality of common-emitter amplifier circuits, and switches SW2, SW1 and SW0 are connected to the respective sides of the bipolar transistors. The emitter sides are held at a ground potential gnd by switching the switches SW2, SW1 and SW0 so that the voltage gain is controlled by selecting the common-emitter amplifier circuits different in voltage gain. A collector current 10 and an emitter degeneration resistance Re between the common-emitter amplifier circuits are so arranged as to have different values. The ratio of the collector current 10 is set inversely proportional to the ratio of the emitter degeneration resistance Re, whereby the collector current 10 decreases when the voltage gain is lowered and a deterioration in distortion characteristics is substantially obviated.

摘要： An output driver circuit for an integrated circuit is disclosed, where the output driver drives an output terminal with a high logic level having a voltage limited from the power supply voltage of the integrated circuit. The limited voltage is provided by applying a limited output high voltage to an output buffer, such that the drive signal applied to the gate of the pull-up transistor in the output driver is limited by the limited output high voltage applied to the output buffer. A voltage reference and regulator circuit for generating the limited output high voltage, or for generating a reference voltage for application to a circuit other than an output buffer and that demands sink current, is also disclosed. The voltage reference and regulator is based on a current mirror, in which the sum of the current in the current mirror is controlled by a bias current source which may be dynamically controlled within the operating cycle or programmed by way of fuses. A sink current path circuit, according to various alternatives, is disclosed as providing an additional sink current path in the event that the limited output high voltage, or reference voltage, exceeds the desired level.
