• Power Management for Integrated RF ICs. Part 1
  By Qui Luu, Analog Devices Analog Dialogue As more building blocks are added to a radio-frequency integrated circuit (RFIC), more sources of noise coupling arise, making power management increasingly important. This article describes how power-supply noise can affect the performance of RFICs. The ADRF6820 quadrature demodulator with integrated phase-locked loop (PLL) and voltage-controlled oscillator (VCO) is used as an example, but the results are broadly applicable to other high-performance ...
• Power Management for Integrated RF ICs. Part 2
  By Qui Luu, Analog Devices Analog Dialogue Part 1 Analysis The plots provide invaluable data on the supply sensitivities at each power pin. VPOS_PLL has the worst power-supply rejection and is therefore the most sensitive power node. This power pin powers the PLL circuitry, including the reference input frequency, phase-frequency detector, and the charge pump. These sensitive function blocks determine the accuracy and phase performance of the LO signal, so any noise coupled on them propagates ...
