A 70 GHz 10.2 mW self-demodulator for OOK modulation in 65-nm CMOS technology [PDF]
IEEE Custom Integrated Circuits Conference 2010, 2010 A 70.86 to 79.29 GHz low-power self-demodulator for on-off-keying (OOK) modulation is realized in TSMC 65-nm CMOS technology. By using a frequency-sweeping injection-locked oscillator (IJLO), the OOK modulated 70 GHz signal is demodulated by itself in a passive mixer and an 8.43 GHz bandwidth is achieved at 10.2 mW power consumption from a 1-V supply ...

Self-demodulation acoustic signatures for nonlinear propagation in glass beads
Comptes Rendus. Mécanique, 2003 The present Note describes some experimental work related to the nonlinear propagation of acoustic waves in granular media such as unconsolidated glass beads. The studied nonlinear effect is a self-demodulation process performed with the operation of the so-called parametric transmitting antenna.
