MTT-23: RFIC

2005 RFIC symposium  

As CMOS technology is rapidly moving towards deep submicron gate lengths, there are several new challenges for the design of RF and analog circuits. One of the main challenges is the drastic reduction on the supply voltage which limits the linearity, dynamic range, and increases the supply ripple sensitivity of RF circuits. With the reduction of the RF supply voltage, noise, ripple and cross-coupling on the power supply is playing a dominant role in the transceiver noise budget. Specifically, synthesizer and reference oscillator phase noise, LNA and mixer noise figure and the adjacent channel requirement of the PA is heavily influenced by the supply noise and spurious content. With increasing drive towards higher level of integration, lower cost, and longer battery life in RF applications, there is a need for efficient monolithic DC-DC power converters. This workshop summarizes the topology tradeoffs that are involved in the implementation of monolithic distributed power management circuits for future generation portable wireless applications. RF supply regulators require high power density, high energy efficiency, low noise and ripple, high PSRR at a wide frequency range, small size, and low cost. The advantages and application areas of low-dropout linear, switched-mode DC-DC converters are examined in light of these requirements
