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 (PV 1) 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： A current-mode controlled DC/DC converter receives an input voltage (Vb) and supplies an output voltage (Vo). A controllable switch (S1) is coupled to an inductor (L) to obtain a periodically varying inductor current (IL) through the inductor (L).

摘要： A common mode voltage generating circuit has a first and a second output terminal (O1, O2) to supply a common mode voltage (Vcm) to a differential output of an amplifier stage (AMP). A first field effect transistor (T1) and a second field effect transistor (T2) have interconnected drains, and both have a source coupled to a supply terminal (Vss). A third field effect transistor (T3) has a source coupled to a drain of the first field effect transistor (T1), a drain coupled to the first output terminal (O1) and to a gate of the first field effect transistor (T1). A fourth field effect transistor (T4) has a source coupled to a drain of the second field effect transistor (T2), a drain coupled to the second output terminal (O2) and to a gate of the second field effect transistor (T2). A fifth field effect transistor (T5) has a gate for receiving a first reference voltage (Vl), and a sixth field effect transistor (T6) has a source coupled to the drain of the fifth field effect transistor (T5), a drain receiving a current (2I) from a current source (CS4), wherein the drain and the gate of the sixth field effect transistor (T6) are interconnected. The third, the fourth and the sixth field effect transistors (T3, T4, T6) have interconnected gates and are biased to operate in their saturation region. The first, second and fifth field effect transistors (T1, T2, T5) are biased to operate in their linear region. The common mode voltage generating circuit further comprises a seventh field effect transistor (T7) with a source coupled to the supply terminal (Vss), a drain coupled to the drain of the fifth field effect transistor (T5), and with a gate which receives a second reference voltage (Vh). The seventh field effect transistor (T7) is biased to operate in its linear region. Bipolar transistors may be used instead of field effect transistors.

摘要： A controller (1) comprises a comparator (10) which compares an input signal (Vo) with a reference signal (Vr) to obtain an error signal (ER). An integrator (11) applies an integrating action on the error signal (ER) to obtain a control signal (ICO). The integrator (11) allows influencing the integrating action. A copy circuit (81) supplies a copy control signal (ICOC) being proportional to the control signal (ICO). A determination circuit (85) determines whether the copy control signal (ICOC) reaches a limit value (IMIN, IMAX). An influencing circuit (83) influences the integrating action to limit the control signal (ICO) when the copy control signal (ICOC) reaches the limit value (IMIN, IMAX).
