摘要： According to one exemplary embodiment, a switching module includes a first harmonic phase tuning filter coupled to a first input of an RF switch. The first harmonic phase tuning filter is configured to provide an output impedance that substantially matches an input impedance of the RF switch at approximately a fundamental frequency and to provide a high impedance at approximately a harmonic frequency generated by the RF switch. The first harmonic phase tuning filter includes an LC circuit coupled between input and output terminals of the first harmonic phase tuning filter and tuned to provide the high impedance at approximately the harmonic frequency generated by the RF switch. The RF switching module further includes a second harmonic phase tuning filter coupled to a second input of the RF switch. The first and second harmonic phase tuning filters can be fabricated on a single semiconductor die.

摘要： According to one exemplary embodiment, a switching module includes a first harmonic phase tuning filter coupled to a first input of an RF switch. The first harmonic phase tuning filter is configured to provide an output impedance that substantially matches an input impedance of the RF switch at approximately a fundamental frequency and to provide a low impedance at approximately a harmonic frequency generated by the RF switch. The first harmonic phase tuning filter includes an LC circuit coupled between an output terminal of the first harmonic phase tuning filter and a ground and tuned to provide the low impedance at approximately the harmonic frequency generated by the RF switch. The RF switching module further includes a second harmonic phase tuning filter coupled to a second input of the RF switch. The first and second harmonic phase tuning filters can be fabricated on a single semiconductor die.

摘要： A uniform tailored electrical field in a multigate field effect D-mode transistor is automatically provided by a feedback circuit which couples drain bias voltages to the gates of a multigate transistor to bias the gates incrementally such that the highest voltage is applied to the gate nearest the drain while the lowest voltage is applied to the gate nearest the source. E-mode multigate FET's carry higher gate voltage on the gate close to the source compared to a gate voltage on a last gate, located close to the drain. The proper distribution of gate voltages improves the transconductance G.sub.m of the transistor and decreases gate capacitance C.sub.gs, which increases the speed of operation of a multigate FETs.
摘要翻译：多重场效应D模式晶体管中的均匀定制的电场由反馈电路自动提供，反馈电路将漏极偏置电压耦合到多晶硅晶体管的栅极，以逐渐偏置栅极，使得最高电压施加到最接近漏极，而最低电压施加到最靠近源极的栅极。与靠近漏极的最后一个栅极上的栅极电压相比，E模式多栅极FET在靠近源极的栅极上承载更高的栅极电压。栅极电压的适当分布提高了晶体管的跨导Gm并降低了栅极电容Cgs，这增加了多栅FET的工作速度。
