Whatever the protocol used by a mobile phone, GSM or TDMA, RF transmitter switching creates the most notorious noise for the power supply. The RF power amplifier switches on and off at a rate of 217 ...

For a system-on-chip (SoC) designs which embed high-resolution audio converters with audio amplifiers, or for a high-sensitivity MEMS, such an amplitude jeopardizes the overall performance of the ...

Power architects engaged in designing systems requiring low output noise and fast transient response — such as RF transmitters, power amplifiers, test systems, displays, designs supporting low-voltage ...

Find a downloadable version of this story in pdf format at the end of the story. Processor-based systems place strenuous voltage regulation requirements on their power supply. In many instances, this ...
