摘要： A power supply monitor circuit is configured to monitor the state of a power supply, such as a battery, while drawing little power from the power supply and using relatively few device components and thus less on-chip resistance. The circuit includes a reference voltage circuit and a comparator circuit. The reference voltage circuit is adapted to receive a power supply voltage signal from the power supply and supplies a reference voltage signal having a voltage magnitude representative of the power supply voltage level. The comparator circuit receives the reference voltage signal from the voltage reference circuit and supplies an output signal having a voltage magnitude of either a first value or a second value, depending on the value of the reference voltage signal. The monitor circuit reduces the power supply voltage signal by about a bandgap, and the comparator circuit is implemented as a current mode bandgap circuit that merges the reference voltage with a comparator function.

摘要： A wireless communication unit comprises a transmitter having a power amplifier biased by a bias circuit and a controller operably coupled to the bias circuit for setting one or more bias levels of the power amplifier. The bias circuit is a single bias circuit and is configured to provide either a current mode bias control of the power amplifier or a voltage mode bias control of the power amplifier in response to a control signal from the controller. In this manner, a single bias control circuit can be used to support applications that benefit from both current mode bias control and voltage mode bias control of the power amplifier.

摘要： A device for regulating the amplitude of a chrominance signal includes a variable gain amplifier having an input receiving a sub-carrier signal, and an output providing a regulated sub-carrier signal. The gain of the amplifier is controlled by two regulation loops. The first regulation loop operates during the duration of the reference burst. The second regulation loop operates during the visible line. Each of these loops include an up/down counter controlled by a clock. A digital-analog converter has an input receiving the output signals from the first and second up/down counters. An output signal from the digital-analog converter is connected to the gain control of the amplifier. The digital-analog amplifier is controlled by another clock.

摘要： The demodulating device for a chrominance signal includes an oscillator with a controlled frequency, and an adjuster for adjusting the oscillator frequency as a function of a charge voltage of a memory capacitor. The adjuster preferably includes a fine adjustment channel to output a first adjustment value that depends on the charge voltage of the memory capacitor, and a coarse adjustment channel to output a second adjustment value. The second adjustment value is modified when the charge voltage of the memory capacitor is not within a given range. The device is used, for example, in integrated SECAM decoders.
