摘要： A high-efficiency single-to-differential amplifier has a first transistor acting as a first amplification stage. A second transistor, a third transistor, a first choke, a second choke, and a first capacitor form a second single-to-differential amplification stage. The first amplification stage receives and amplifies an input signal, outputs the amplified signal to the second single-to-differential amplification stage through a coupling module, and concurrently provides DC bias current to the second single-to-differential amplification stage through a tank. The second single-to-differential amplification stage reuses DC current of the first amplification stage, amplifies the output signal of the first amplification stage, and transfers it to a differential output.

摘要： An active mixer with self-adaptive bias feedback is described and resolves a poor linearity, inconvenient design of a bias circuit, and other defects of a conventional mixer. The dual self-feedback bias structure according to this invention is used. The active mixer with self-adaptive bias feedback has a power supply, an RF input match/drive unit, a local oscillator input match/drive unit, a mixer core unit, a self-adaptive twin bias circuit and an IF output match/buffer unit. This invention improves the linearity of a conventional mixer and does not affect other characteristics. There are fewer components in this invention; an area of the mixer is thus smaller. Further, this invention may improve temperature response, increase yield factor, and lower unit cost. The dual self-feedback bias structure is designed for further application to other semiconductor manufacturing processes, components, and microwave products.

摘要： A linearized bias circuit with adaptation resolves the problem happening to the power amplifier with conventional bias circuit that the DC and AC characteristics of the power amplifier shift or even deteriorate due to a temperature variation. The linearized bias circuit with adaptation has a reference voltage source, a first voltage source, a first resistor, a second resistor, a first NPN transistor, a second NPN transistor, and a third NPN transistor. The present invention has the characteristics of bias current temperature compensation, gain and phase compensations to achieve high linearity for the conventional power amplifier and reducing the DC consumption power. At the same time, the quantity of the required elements and layout area in the present invention are small so that the design complexity can be reduced for improving yield, reducing IC layout area, and reducing cost.

摘要： A wide area atmospheric pressure plasma jet apparatus including a transmission mechanism, a plasma housing and two plasma-generating devices is provided. The transmission mechanism includes a rotation output end that has a center axis. The plasma housing has an opening. The plasma housing further has a air-attracting hole near the rotation output end and extended from an outer wall of the plasma housing to the interior of the plasma housing, so that the heat of the plasma housing can be dissipated due to the generated gas circulation. The plasma-generating devices are disposed within the plasma housing and connected with the rotation output end. Each of the plasma-generating devices has a plasma nozzle located at the opening and tilts from the center axis. When the rotation output end drives the plasma-generating devices to rotate, two plasma beams are obliquely ejected from the plasma nozzle and the plasma processing area is increased.
