A transmitter consisting of a voltage
controlled oscillator (VCO) and power amplifier
(PA) for the 400 MHz Medical Implanted Communication
System band (MICS) was built in a standard
0.35-μm CMOS process. A push pull architecture
was used for both the VCO and the PA. Two
off-chip inductors were needed.
The design was optimized for 400 μW output
power at 3 V supply, which resulted in an efficiency
of 26 %. This gives a total power consumption of
1.6 mW, of which the VCO uses about 0.3 mW.
