    摘要： An auxiliary voltage generating unit (200) for a radio frequency switch (100) includes a first input and a second input respectively configured to receive a first control signal and a second control signal, characterized in that the first control signal and the second control signal are configured to control which one of a plurality of paths in the radio frequency switch (100) is enabled, and at least one output, configured to output an auxiliary voltage, derived from at least one of the first control signal or the second control signal, that is used to operate the radio frequency switch (100). The auxiliary voltage may be a bias voltage and/or a voltage used to power an inverter (150) used to enable a selected branch as an isolation branch or shunt branch.

    摘要： A switch device includes a switch unit (SU1), an adjustment switch (SWA), an impedance element (R1), a node (N2) and a detection unit (DU). A first terminal and a second terminal of the adjustment switch (SWA) are respectively coupled to a second terminal of the switch unit (SU1) and a reference voltage terminal (150). A first terminal and a second terminal of the impedance element (R1) are respectively coupled to the first terminal and the second terminal of the adjustment switch (SWA). The detection unit (DU) is coupled to the node (N2), and a control terminal of the switch unit (SU1) and a control terminal of the adjustment switch (SWA). The detection unit (DU) detects a node signal (SN) at the node (N2) to accordingly control the switch unit (SU1) and the adjustment switch (SWA).

    摘要： A voltage controlled circuit includes a tracking circuit (10), an operational amplifier (12), a transistor, a feedback circuit (17) and a sample and hold circuit (14). The tracking circuit (10) generates an updated enabling voltage (V'set) according to an enabling voltage (Vset), a sample enabling voltage (Vset max) and a sample reference voltage (Vclamp). The operational amplifier (12) output a control voltage according to an input voltage (V1) and a feedback voltage (V2). The transistor includes a control terminal receiving the control voltage, a first terminal receiving a reference voltage (VBAT), and a second terminal outputting a regulated voltage (Vreg). The feedback circuit (17) generates the feedback voltage (V2) according to the regulated voltage (Vreg). The sample and hold circuit (14) samples the input voltage (V1) to generate the sample enabling voltage (Vset_max), and samples the feedback voltage (V2) to generate the sample reference voltage (Vclamp).

    摘要： A voltage generator (100) includes an oscillator (130), a charge pump (140) having an input and an output, the input of the charge pump (140) being coupled to the output of the oscillator (130), a first resistor (R1) connected to the output of the charge pump (140), a second resistor (R2) connected to the first resistor (R1), a smoothing capacitor (C1) connected to the second resistor (R2), and a shorting element (150) connected in parallel with the second resistor (R2). When the shorting element is turned on, the second resistor (R2) is bypassed. By including an adjustable regulated voltage regulator (160), an adjustable bias current generator (160) and a size-adjustable inverter module (170), the voltage generator (100) is able to manipulate the speed of voltage generation.
