The continuous administration of low levels of melatonin via intraperitoneally placed Silastic capsules either (i) shortened the free-running period of activity or (ii) induced continuous activity in house sparrows (Passer domesticus) maintained in constant darkness. After the melatonin-filled capsules were removed, the period of the circadian rhythm of(More)
A transmitter for rotational spectroscopy using a fractional-N PLL (FNPLL) that generates frequency shift keyed signals from 85 to 127 GHz (39% tuning range) with a fine frequency step of ~570 Hz and settling time of ~10 μS is demonstrated. Implemented in 65-nm CMOS, the FNPLL delivers greater than 5 μW of output power, and achieves measured(More)
A fully integrated CMOS receiver for mm-wave rotational spectroscopy is demonstrated. The receiver consists of a sub-harmonic mixer based receiving front-end which down-converts 225-280 GHz RF input to 20 GHz intermediate frequency, a 20-GHz AM demodulator followed by a baseband buffer amplifier, and an 122-139 GHz local oscillator chain which is comprised(More)
