The Electric Mayhem's Bluetooth LNA Page

OVERVIEW:
    Our group's task was to design three key components of a 2.4 to 2.5 GHz, Q-enhanced, Low Noise Amplifier (LNA) and local oscillator that are to be part of a completely integrated Bluetooth transmitter/reciever architecture that is being developed here at Kansas State University.  Engineer One's task was to design the core amplifier and associated local oscillator using pmos in order to improve noise figure over previous designs.  Engineer Two's task was to design the Q and frequency tuning circuits to be used by the LNA and oscillator.  Engineer Three's task was to debug/redesign the divide by 16 circuit used in the oscillator's phase locked frequency control loop.  These tasks will be discussed in detail in each engineer's individual page, reached at the bottom of this page.  The overall block diagram for the LNA/Oscillator can be seen below, as well as a simplified circuit schematic of the LNA design and basic tuning components.
