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 (PSO1, PSO2) to supply a first power supply voltage (PV1) with a first level and a second power supply voltage (PV2) with a second level, higher than the first level. A switching circuit (SC) is arranged between the power supply outputs (PSOI, PSQ2) and the power supply input (PI) to supply a selected one of the first power supply voltage (PV1) or the second power supply voltage (PV2) 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 (PV1) 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:1e output power (Po) and succeeding the first power change command (PC), to supply either the first power supply voltage (PV1) or the second power supply voltage (PV2) 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, PV2) to always have available one of the power supply voltages with a level suitable for increasing the output power (P0) substantially instantaneously.

摘要： An electronic circuit comprising an amplifier includes an output terminal (OUT) for supplying an output signal (Vout) to a load, the amplifier comprising an output transistor (N2, P1) having a first main terminal coupled to a supply voltage terminal (VSS, VDD) of the amplifier, a second main terminal coupled to the output terminal (OUT), and a control terminal. In order to avoid that the output transistor (N2, P1) can enter its linear state which would cause the amplifier to act unacceptably slow for some purposes, the electronic circuit further comprises a controller adapted to prevent the output transistor (N2, P1) to enter its linear state whereby the controller is arranged for reducing a control voltage (Vcntrl) between the control terminal and the first main terminal when an output voltage (Vout) between the second main terminal and the first main terminal is below a defined level.

摘要： An electronic circuit for supplying a common mode voltage to a differential output of an amplifier stage (AMPSTG). The common mode voltage at the terminals (1) and (2) is approximately equal to the reference voltage (VCM). Transistors (T1-T4) are biased in their linear region whereas transistors (T5-T8) are biased in their saturation region. In order to choose the lowest possible reference voltage (VCM), the dimensioning of the transistors (T1-T4) is such that the currents through the transistors (T1-T3) have equal current densities, and the current through the transistor (T4) has a current density which is a factor N smaller than the former current densities. The factor N is determined by the ratio of the nominal value of the current through the transistor (T1) and the minimum value of the current through the transistor (T1).
