Abstract :
A driver amplifier for Bluetooth application is implemented in 0.35 μm CMOS technology. This paper presents a driver amplifier with high linearity and gain, and demonstrates that linearity has a quality factor dependency of inductive load. The linearity difference of the driver amplifier between the external and on-chip inductive load is analyzed analytically and it is confirmed by a measurement. The measurement shows that the driver amplifier with an off-chip inductive load has a higher linearity of 3.6 dB and a higher gain of 1.6 dB than the driver amplifier with the on-chip inductive load has.
