摘要: A low capacitance n-channel analog switch circuit, a p-channel analog switch circuit, and a full CMOS transmission gate (T-gate) circuit are described. Resistive decoupling can be used to isolate the switch or T-gate from AC grounds, such as one or more switch control signal inputs or supply voltages. A semiconductor region that is separated from a body region of a pass field-effect transistor (FET) can be coupled to or driven to a voltage similar to the input voltage or other desired voltage to help reduce parasitic capacitance of the switch or T-gate. The switch or T-gate can have improved frequency bandwidth or frequency response. The switch can be useful in a programmable gain amplifier (PGA) or programmable gain instrumentation amplifier (PGIA) or other circuit in which excessive switch capacitance could degrade circuit performance.

摘要: A monolithically integrated semiconductor switch, particularly a circuit breaker, has regenerative turn-off behavior. The semiconductor switch has two monolithically integrated field effect transistors, for example a p-JFET and a n-JFET. The source electrodes of both JFETs and the well region of the n-JFET are short circuited. In addition, the gate electrodes of both JFETs and the drain electrode of the p-JFET are short-circuited via the cathode. In contrast, the well region of the p-JFET is short-circuited to the anode. In this way, a monolithically integrated semiconductor switch is created which turns off automatically when a certain anode voltage level or a certain anode current level is exceeded. The threshold values for the anode voltage and the anode current can be set by appropriate dimensioning of the elements. In this way, it is possible to achieve blocking strengths of up to 200 kV with fast response behavior.

摘要: A system for providing a first voltage generated by a main supply and a second voltage generated by a battery to an integrated circuit (IC) includes supply-selection, control logic and switching circuits. The supply-selection circuit includes first, second, and third transistors. The switching circuit includes fourth and fifth transistors that supply the first and second voltages to the IC when switched on. The supply-selection circuit selects and provides the higher of the first and second voltages to body terminals of the fourth and fifth transistors for maintaining required body-bias voltage conditions. The control logic circuit generates a first control signal as long as the first voltage is within a predetermined range for keeping the fourth transistor switched on and a second control signal when the first voltage is not within the predetermined range for switching on the fifth transistor to supply the second voltage.
