Abstract:
A radio receiver front-end includes a tunable antenna interface and a low noise amplifying section. The tunable antenna interface is operably coupled to receive a wide bandwidth signal from an antenna, wherein the wide bandwidth signal includes a plurality of channel signals, and wherein the tunable antenna interface is tuned to pass a selected one of the plurality of channel signals substantially unattenuated and to attenuate remaining ones of the plurality of channel signals to produce a filtered wide bandwidth signal. The low noise amplifying section is operably coupled to amplify the filtered wide bandwidth signal to produce a filtered and amplified wide bandwidth signal.

Abstract:
A backlight control module includes a gain module, a variable voltage reference, a comparator, and a pulse width modulator. The gain module is coupled to amplify a representation of LED current to produce an amplified current sense signal. The variable voltage reference source is coupled to produce a reference voltage based on the backlight setting to produce a representation of the backlight setting. The comparator is coupled to compare the reference voltage with the amplified current sense signal to produce the comparison signal. The pulse width modulator is coupled to produce a pulse width modulated (PWM) signal as the brightness control signal based on the comparison signal, wherein the brightness control signal is provided to an off-chip variable supply voltage source that provides power to the off-chip LED.
