摘要： There is provided a linear amplifier capable of suppressing a reduction in bandwidth and reducing a ripple voltage by using a source follower and a local feedback loop. The linear amplifier includes an amplifier amplifying an input signal according to a difference in signal level between the input signal and a feedback signal, and a buffer buffering a signal amplified in the amplifier by a source follow method, suppressing a reduction in bandwidth of the signal, outputting the signal, and providing the bufferred signal to the amplifier as the feedback signal.

摘要： An RF switch circuit includes an RF switch including a first NMOS switch formed on a chip substrate, a switch controller including a second NMOS switch and a PMOS switch formed on the substrate, for controlling the RF switch, and a limiter including a deep N-type well diode formed on the substrate, for limiting an RF signal level transferred from the RF switch to the switch controller through the substrate. The first NMOS switch includes a first N-type terminal formed on a deep N-type well substrate formed on the substrate, for receiving a driving power through a first floating resistor, a P-type terminal for receiving a body power through a second floating resistor, and two second N-type terminals for receiving a gate power through a third floating resistor. The P-type and two second N-type terminals are formed on a P-type substrate formed on the deep N-type well substrate.
