摘要: An amplifier element amplifies RF signals. An emitter follower unit drives the amplifier element at a constant voltage corresponding to a reference voltage supplied to a reference terminal from outside. A current injection unit drives the amplifier element at a constant current corresponding to the reference voltage. An analog control unit analogically controls the output voltage of the emitter follower unit in correspondence with the control voltage supplied to a control terminal from outside. A mode switching unit switches whether the emitter follower unit is operated or not in correspondence with the control voltage.

摘要: A method for using a film formation apparatus includes performing film formation of a product film selected from the group consisting of a silicon nitride film and a silicon oxynitride film on a target substrate within a reaction chamber of the film formation apparatus; and unloading the target substrate from the reaction chamber. Thereafter, the method includes first heating an inner surface of the reaction chamber at a post process temperature while supplying a post process gas for nitridation into the reaction chamber, thereby performing nitridation of a by-product film deposited on the inner surface of the reaction chamber; then rapidly cooling the inner surface of the reaction chamber, thereby cracking the by-product film by a thermal stress; and then forcibly exhausting gas from inside the reaction chamber to carry the by-product film, thus peeled off from the inner surface.

摘要: A final-stage power amplification transistor is formed of unit transistors arranged in a mixed manner in a region in which the final output amplification transistors for a multi-band power amplifier is formed. Furthermore, an inductance element is connected between output signal lines to which the final output stage transistors are coupled. Thus, the final-stage transistors in a dual band power amplifier can be made free from current concentration due to heat generation without impairing inter-band isolation.

摘要: A differential amplifier receiving a first input signal and a second input signal, respectively, and amplifying voltage difference between the first and second input signals to output an output signal includes a first source follower circuit receiving an external data signal as the first input signal, and having an output node; a second source following circuit having a constant current source FET and receiving a reference voltage as the second input signal; and a bias circuit providing a signal having the same phase as the data signal from the output node of the first source follower circuit and inputting that signal to a gate terminal of the constant current source FET of the second source follower circuit. By providing an input interface circuit connected to an external signal source and producing a phase inversion signal from an input data signal in a differential amplifier or in a first stage differential amplifier connected to other amplifiers in multiple stages, the differential gain can be improved to a value approximately equal to that obtained when differential inputs are supplied.
