摘要： A high gain, low voltage differential amplifier exhibiting extremely low common mode sensitivities includes a load element exhibiting a high differential resistance, but a low common mode resistance. The load element contains a positive differential load resistance and a negative differential load resistance, which offsets the positive differential load resistance. The output common mode level of the differential amplifier is one p-channel source to gate voltage drop below the power supply voltage prohibiting the common mode output voltage from drifting far from an active level. The differential amplifier also has application for use in a differential charge pump circuit. The high differential impedance of the differential amplifier allows the attainment of extremely small leakage, while a low common-mode impedance results in simplified biasing.

摘要： A current mirror circuit capable of accurately setting the ratio between input current and output current. The circuit includes a plurality of input terminals and a plurality of output terminals. A plurality of transistor pairs is provided with the first transistor of each pair having its collector connected to an input terminal. In addition, the collector of each first transistor in each pair is coupled to its own base. The bases of the transistors in each pair are coupled together, while the collector of the second transistor in each pair is coupled to an output terminal. The transistors connected to input terminals have their emitters coupled together and grounded through a first resistor.

摘要： A signal-receiving and signal-processing unit connected to one or several conductors is configured to transmit information-carrying signals in the form of voltage pulses. The conductor is connected to a transistor in a signal-receiving circuit to affect a current by using variations in the voltage pulses and the voltage value of a pulse. The current is in the form of pulses that pass through the transistor. The current is generated by the voltage pulse variations and voltage level. The current is given a signal-adapted information-carrying form by a signal-processing circuit. The transistor in the signal-receiving circuit is coordinated with at least one other transistor so that together they form a current mirror circuit.

摘要： An impedance neutralization circuit produces correction currents to compensate for the effects of parasitic impedance on the output voltage of an amplifier. In the described embodiment, the neutralization circuit includes a pair of emitter followers, one coupled to the collector of each transistor of a common base amplifier for sensing the output voltage at each collector. A pair of transistors are coupled one to each emitter follower for applying the sensed voltage across a neutralizing impedance proportional to the parasitic impedance seen at the collector of the opposite transistor of the common base amplifier. The voltage applied across the neutralizing impedances produces a correction current. The correction current is summed with a distortion current of proportional amount but opposite sign produced by the output voltage applied across the parasitic impedance to produce a substantially error-free output voltage.
