摘要： An apparatus for harvesting energy from motion of a human or animal body segment and providing the energy to an electrical load is disclosed. The apparatus comprises a generator operatively coupled to the body segment such that particular movement of the body segment causes the generator to output a generator current and to oppose the particular movement of the body segment with a generator torque. An electrical load is coupled to receive the generator current. A control system is operatively connected between the generator and the electrical load and is configured to control the generator torque during the particular movement of the body segment. Corresponding methods are also disclosed.

摘要： An amplifier circuit includes first (7A) and second (7B) operational amplifiers connected in a parallel configuration. A first terminal (12) of a first input resistor (5) is coupled to one input of both of the first (7A) and second (7B) amplifiers. A first terminal (15) of a second input resistor (6) is coupled to another input of both of the first (7A) and second (7B) amplifiers. A differential input voltage is applied between the second terminals of the first and second input resistors. The output signals of the first (7A) and second (7B) operational amplifiers are combined to produce an output signal (11AB) representative of feedback currents produced in the first (5) and second (6) input resistors. Upper and lower common mode input voltage ranges associated with the differential input voltage extend substantially above and below the upper and lower supply voltages, respectively, of the amplifier circuit.

摘要： An integrated circuit photodetector includes a transimpedance amplifier including a differential amplifier stage with PNP emitter-coupled transistors and a PNP input transistor which are biased only by base currents of the emitter-coupled transistors, to achieve low input bias current. Low noise operation is achieved by bypass capacitors coupled between the bases and emitters of the input transistors, respectively. A constant current source supplies a current which develops a small pedestal voltage across a resistor to bias the non-inverting input of the transimpedance amplifier so as to avoid nonlinear amplification of low level light signals. A positively biased N-type guard tub surrounds the photodetector, which is formed in a junction-isolated N region on a P substrate, to collect electrons generated in the substrate by deep-penetrating IR light to prevent them from causing amplification errors. In one embodiment, a feedback network includes a resistor connected between the output of a buffer driven by the transimpedance amplifier and an inverting input thereof, and a capacitor connected between the output and inverting input of the transimpedance amplifier to provide low noise, fast settling operation.

摘要： An integrated circuit current shunt amplifier (2A) includes an amplifier (9) having a (+) input connected to a first terminal (5A) of a shunt resistor (RSHUNT). An output transistor (24) has a gate coupled to an output of the amplifier, a source coupled to a (−) input of the amplifier, and a drain coupled to a first terminal of an output resistor (ROUT). A gain resistor (RGAIN) is coupled between the (−) input of the amplifier and a second terminal of the shunt resistor. The gain resistor has a temperature coefficient which is essentially the same as that of the shunt resistor. A voltage regulator (26) can be coupled between the second terminal of the shunt resistor and a low-side supply voltage terminal (27) of the amplifier. A charge pump (30) can provide a below-ground voltage on a second terminal of the output resistor. A difference amplifier (31) coupled to the drain and referenced to the below-ground voltage produces an output voltage (Vout) referenced to ground.
