The Concept of CMOS OOK Transmitter
Using Low Voltage Self-Oscillating Active Inductor.
In: International Conference on Signals and Electronic Systems (ICSES) 2010, 7th-10th September 2010, Gliwice, Poland.
This paper presents a low voltage, On-Off Keying
(OOK) CMOS integrated transmitter for ISM 434 MHz
biomedical applications using a concept of a novel self-oscillating
(degenerated) active inductor. A thorough theoretical analysis of
the oscillator is presented, together with simulated results using
UMC 90 nm 1P9M RF process libraries. The proposed oscillator
achieves an average phase noise of -93 dBc/Hz at 1 MHz offset
from 434 MHz carrier frequency, with a relative tuning range
of 26% to compensate for process variations. The transmitter
allows modulation speeds up to 100 Mbps with RF output power
of -4 dBm to 50 Ω load from 1 V power supply.
