摘要： An electronic circuit includes a differential pair (T1, T2) provided with a degeneration device (DGMNS) for degenerating a transconductance of the differential pair (T1, T2), and an auxiliary circuit (B) for supplying a control voltage (U) to a control terminal (CNTRL) of the degeneration device (DGMNS). The auxiliary circuit (B) also accomplishes a DC-biasing of the differential pair (T1, T2). The control voltage (U) and the DC-biasing are such that the transconductance of the differential pair (T1, T2) is virtually independent of the value of the control voltage (U) and virtually independent of the DC-biasing of the differential pair (T1, T2). The auxiliary circuit (B) comprises a further differential pair (T3, T4) provided with a further degeneration device (FDGMNS) for degenerating a transconductance of the further differential pair (T3, T4). The auxiliary circuit (B) is arranged for supplying a further control voltage (UF) to a control terminal (FCNTRL) of the further degeneration device (FDGMNS). The control voltage (U) is dependent on the further control voltage (UF). The further control voltage (UF) and the control voltage (U) can, for instance, be the same voltage. The auxiliary circuit (B) includes a device (B2) for generating a desired current ratio (n) between a first branch (Br1) and a second branch (Br2) of the further differential pair (T3, T4). The auxiliary circuit (B) includes a device (B1) for generating a first DC-voltage (VP) to a first input terminal of the further differential pair (T3, T4), and a second DC-voltage (VM) to a second input terminal of the further differential pair (T3, T4).

摘要： The invention relates to a magnetic sensor device (100) with a primary and secondary detection unit (P, S), each of which comprises a magnetic sensor element and a magnetic field generator. In a preferred embodiment, the magnetic sensor elements are GMR elements (12, 22) with the same sensitive directions (D12, D22), and the magnetic field generators are parallel wires (11, 21) which are supplied by an evaluation and control unit (40) with anti-parallel magnetic excitation currents. The magnetic excitation currents generate magnetic excitation fields (Bn, B2i) with opposite sense of rotation which in turn induce oppositely directed magnetic reaction fields (B'11, B'21) in magnetized particles (1) provided in an investigation region (2). The magnetic reaction fields (B'11, B'21) therefore have opposite effects on the GMR elements, yielding an increase in the difference (Δ) between the output signals of these elements. In a preferred embodiment, four detection units are arranged in a Wheatstone bridge.

摘要： The present invention relates to an improved PTAT current source and a respective method for generating a PTAT current. Opportune collector currents are generated and forced in two transistors exploiting the logarithmic relation between the base-emitter voltage and the collector current of a transistor. A resistor connected between the base terminals of said two transistors senses a voltage difference between the base-emitter voltages of the two transistors, which can have either the same or different areas. A fraction of the current flowing through the resistor is forced into a transistor collector and mirrored by an output transistor for providing an output current. By this principle an all npn-transistor PTAT current source can be provided that does not need pup transistors as in conventional PTAT current sources. The invention is generally applicable to a variety of different types of integrated circuits needing a PTAT current reference.

摘要： A transmitter comprises a power amplifier (PA) with a power supply input (PI) and an output (PAO) to supply a transmission signal (Vo) with an output power (Po). A power supply (PS) has power supply outputs (PSO 1 , PSO 2 ) to supply a first power supply voltage (PV 1 ) with a first level and a second power supply voltage (PV 2 ) with a second level, higher than the first level. A switching circuit (SC) is arranged between the power supply outputs (PSOI, PSQ 2 ) and the power supply input (PI) to supply a selected one of the first power supply voltage (PV 1 ) or the second power supply voltage (PV 2 ) to the power amplifier (PA). A controller (CO) supplies a control signal to the switching circuit (SC) in response to a first power change command (PC) indicating a first desired level of the output power (Po), to supply the first power supply voltage (PV 1 ) to the power supply input (PI). The controller (CO) supplies the control signal to the switching circuit (SC) in response to a second power change command (PC) indicating a second desired level of t: 1 e output power (Po) and succeeding the first power change command (PC), to supply either the first power supply voltage (PV 1 ) or the second power supply voltage (PV 2 ) to the amplifier power supply input (PI) depending on values of said first desired level and said second desired level. The controller (CO) controls the power supply (PS) to vary a level of at least one of the power supply voltages (PV, PV 2 ) to always have available one of the power supply voltages with a level suitable for increasing the output power (P 0 ) substantially instantaneously.
