AN AMPLIFIER CIRCUIT, A TRANSMITTER AND A WIRELESS TELEPHONE |
摘要 |
An amplifier circuit, particularly for RF-purposes includes a main current stream of a controllable RF-semiconductor device having a control input, a control means having a control output coupled to the control input for controlling the main current stream, and a compensation circuit having a compensation output coupled to the control input for compensating the controllable semiconductor device. The compensation circuit is constructed so as to be temporarily active during a period of time wherein the control means do not supply a control output signal to the control input of the controllable semiconductor device. This provides a suitable solution for IC's and for dealing with DC-adjustment disturbances in a low DC-current dissipating manner caused by a lack of pull-down capability when the amplifier circuit operates at very high frequencies or at relatively large amplitudes. |
