摘要：

A 5.7 GHz fully integrated complementary LC voltage controlled oscillator (CLC VCO) has been designed in an inexpensive 0.25-mu m digital CMOS process for low power neurosensory application. Consuming only 2mA of current from a 2.5 V power supply, the CLC VCO achieves a measured single-side band phase noise of -92.75 dBc/Hz and -97.6 dB/Hz at 600 KHz and 1.0 MHz offset frequency, respectively. The CLC VCO is able to output -5dBm of power at the single-ended output to a SO-Ohm load to meet demands or high-date rate short reach On-Off Keying (OOK) wireless transmission. Various low power techniques used to improve phase noise in the LC VCO are also discussed.
