Frequency Dependent Specific Heat from Thermal Effusion in Spherical Geometry [PDF]
, 2010 We present a novel method of measuring the frequency dependent specific heat at the glass transition applied to 5-polyphenyl-4-ether. The method employs thermal waves effusing radially out from the surface of a spherical thermistor that acts as both a ...

CMOS OTA-C high-frequency sinusoidal oscillators [PDF]
, 1991 Several topology families are given to implement practical CMOS sinusoidal oscillators by using operational transconductance amplifier-capacitor (OTA-C) techniques. Design techniques are proposed taking into account the CMOS OTA's dominant nonidealities.

Frequency tuning loop for VCOs [PDF]
, 1991 A frequency tuning circuit is introduced for VCOs (voltage-controlled oscillators) so that the final relationship between oscillating frequency and input control voltage is fixed and independent of nonidealities.
