Abstract: A power supply ready indicator circuit is described. The power supply ready indicator circuit includes a first power-supply-ready-input interfacing with a first power supply rail; a second power-supply-ready-input interfacing with a second power supply rail; and a power ready indicator output. The power supply ready indicator circuit is configured to divide the voltage on the first power supply rail, and to compare the divided voltage with the second power supply rail voltage. The power supply ready indicator circuit generates a power ready signal on the power ready indicator output in response to the divided voltage value being greater than the second power supply rail voltage value. The final value of the first power supply rail voltage is greater than the final value of the second power supply rail voltage.

Abstract: A two-stage RF amplifier is provided. The first stage is a common-emitter transistor arrangement with a purely reactive degeneration impedance and an output impedance with a reactive component matched in frequency response to the degeneration impedance. The second stage is a buffer amplifier. The first amplifier can be designed for high gain which is flat over frequency by virtue of the reactive degeneration impedance. The first amplifier provides input matching, and the buffer provides output matching, with decoupling between the input and output.

Abstract: An antenna switch circuit and an antenna circuit switching method. The circuit includes an antenna port, a termination port (e.g., for disposal of power reflected back from an antenna and received through the antenna port in a transmit mode), and a receive port (e.g., for receiving a signal from the antenna port via the antenna switch circuit in a receive mode). The circuit also includes a first switch coupled between the antenna port and the termination port. The circuit further includes a resonant inductance coupled between the receive port and the node located between the antenna port and the first switch. The circuit also includes a second switch coupled between a reference potential and a node located between the resonant inductance and the receive port.

Abstract: A matching circuit comprising: an input-terminal configured to be connected to an active-circuit; an output-terminal configured to be connected to a downstream component; a current-source configured to provide a disabled-current; one or more diode-modules, each comprising a diode and a biasing-resistor in parallel with each other; and a reactive-matching-component that has a reactive impedance. The current source is configured to pass the disabled-current through the one or more diode-modules and the reactive-matching-component when the matching circuit is in a disabled-mode of operation such that they contribute to the impedance of the matching circuit between the input-terminal and the output-terminal.
