摘要： A feedback-type variable gain amplifier including a first field effect transistor, a feedback circuit, and a load circuit. The first field effect transistor receives an input voltage signal through an input node, amplifies the input voltage signal, and outputs the amplified input voltage signal through an output node. The feedback circuit is coupled between the input node and the output node, and generates feedback impedance that is changed in response to a control signal. The load circuit is coupled between the output node and a voltage source, and generates load impedance that is changed in response to the control signal to cancel a change of input impedance due to a change of the feedback impedance. Therefore, since the input impedance is not changed when the gain of the amplifier is changed, a voltage standing wave ratio is good, and a range of gain control is broad.

摘要： A voltage reference circuit and a current reference circuit using a vertical bipolar junction transistor (BJT) implemented by a deep N-well complementary metal-oxide semiconductor (CMOS) process, wherein the voltage reference circuit generates a constant reference voltage regardless of temperature and includes an amplifier element having a positive input terminal and a negative input terminal, a first transistor, and a second transistor. The first transistor is electrically connected to the positive input terminal and the second transistor is electrically connected to the negative input terminal. Each of the first and second transistors is a vertical BJT implemented by a deep N-well CMOS process, and the reference voltage is calculated by adding a base-emitter voltage of one of the first and second transistors to a value obtained by multiplying a thermal voltage by a predetermined factor. Accordingly, circuits having better reproducibility, uniformity, and device matching than circuits that use a lateral NPN/PNP device or substrate NPN/PNP device manufactured using a CMOS process are provided.
