description |
Recent efforts in the design of integrated circuits for RF communication
transceivers have focused on achieving higher levels of integration by including more and
more analog functional blocks onto a single silicon CMOS chip. One of the final blocks
that have yet to be successfully integrated is the power amplifier. The power amplifier is
the final functional block in the transmit path and its function is to amplify the signal to
be transmitted to the required transmit power level. In general, power amplifiers are
difficult to integrate in CMOS because of technology limitations that severely limit the
efficiency of the power amplifier. This thesis describes theoretical analysis and circuit
techniques for the design and implementation of RF Class C power amplifier in CMOS
technologies. There are very few methods exist for designing Class C power amplifier in
the past, much of the design process has been empirical. The theoretical work in this
thesis attempts to describe a method for designing a Class C power amplifier in CMOS
without resorting to blind use of a circuit simulator. A 900MHz CMOS power amplifier
was designed using Silterra 0.18µm RF MOSFET. This design is simulated using
Cadence Design tool. In this simulation, the peak efficiency of the power amplifier was
37.7%. The power amplifier did meet the spectral mask requirements of CDMA (Code
Division Multiple Access) cellular communications system for which it was designed.
The power gain that had been achieved is 34.74 dB and meets the power amplifier
specification for CDMA application. |
