Abstract: The present disclosure relates to envelope power supply calibration of a multi-mode RF power amplifier (PA) to ensure adequate headroom when operating using one of multiple communications modes. The communications modes may include multiple modulation modes, a half-duplex mode, a full-duplex mode, or any combination thereof. As such, each communications mode may have specific peak-to-average power and linearity requirements for the multi-mode RF PA. As a result, each communications mode may have corresponding envelope power supply headroom requirements. The calibration may include determining a saturation operating constraint based on calibration data obtained during saturated operation of the multi-mode RF PA. During operation of the multi-mode RF PA, the envelope power supply may be restricted to provide a minimum allowable magnitude based on an RF signal level of the multi-mode RF PA, the communications mode, and the saturation operating constraint to provide adequate headroom.

Abstract: A digital input circuit includes a series connection of a current limiter and a switch having a switch control input coupled between a signal input and ground, and a logic level shifter coupled to the signal input and having a switch control output coupled to the switch control input and a signal output, where a maximum amplitude at the signal input is greater than a maximum amplitude at the signal output. A digital input method includes coupling an input signal to ground with a current limiter by closing an electronic switch, providing an output signal responsive to the input signal, where a maximum amplitude of the input signal is greater than a maximum amplitude of the output signal, by latching the output signal while the input signal is above a threshold voltage and opening the electronic switch after the output signal is latched.

Abstract: The electronic circuit (1) for measuring at least one physical parameter supplies an analogue output measurement signal (SA) dependent upon the value of a supply voltage. The circuit includes a sensor interface (2) connected to a sensor (C) for supplying an analogue measurement signal (Vm) which is then filtered. The circuit further includes an analogue-digital converter (8) for digitally converting the filtered signal (Sm), a digital signal control and processing unit (9) for receiving a converted signal from the converter, and supplying a digital measurement signal (SD). The sensor interface, the analogue-digital converter and the processing unit (9) are powered by a regulated voltage supplied by a voltage regulator (4). The analogue and digital measurement signals are thus independent of any variation in the supply voltage (VCC) of the electronic unit. A ratiometric unit, which may be an analogue multiplier (5) or a digital-analogue converter, is powered for example by the supply voltage source (Bat) in order to recreate the ratiometry on an analogue output measurement signal (SA) on the basis of the analogue (Sm) or digital (SD) measurement signal.
