Log-domain All-pass Filter-based Multiphase Sinusoidal Oscillators [PDF]
, 2013 Log-domain current-mode multiphase sinusoidal oscillators based on all-pass filters are presented in this paper. The first-order differential equation is used for obtaining inverting and non-inverting all-pass filters.

Active Power Filters for Harmonic Elimination and Power Quality Improvement
, 2011 The explosive growth in consumer electronics and domestic appliances has generated a major concern in the electricity supply industry, (Bollen, 1999). Due to its interface circuit (a diode bridge, followed by a large DC capacitor), these appliances draw current only near the peak of the mains voltage.
