Patent GB-2336492-B (GB)
Title: Voltage controlled oscillator
Inventor: LICHTERFELD STEFAN
IPC: H03B5/12
Filed: 1998-04-15
Granted: 2000-06-07
Abstract: A voltage controlled oscillator based on the Colpitt's design is provided. An inductor Lc is provided in parallel to one Cs of a pair of series connected capacitors Cs, Cd. The presence of the inductor Lc modifies the impedance ratio of the pair of series connected capacitors Cs, Cd by introducing a frequency dependence. This frequency dependence mitigates frequency dependent losses in a tuned circuit Lr, Ct in the voltage controlled oscillator. The invention provides an enhanced output signal over the frequency range of operation of the voltage controlled oscillator. The invention also improves the modulation of the voltage controlled oscillator's output signal which can be achieved by a separate modulation circuit Cm, Rm, Vm. The oscillator may form part of a mobile radio receiver or mobile telephone.

Abstract: Fluorinated ion exchange polymers which have both pendant side chains containing carboxylic groups and pendant side chains which contain sulfonyl groups, when used in the form of membranes to separate the anode and cathode compartments of an electrolysis cell, permit operation at high current efficiency.  They are made by oxidation of flourinated polymers which have pendant side chains containing sulfinic groups, or both sufinic and sulfonyl groups.  The fluorinated polymers which have pendant side chains containing sulfinic groups, or both sufinic and sulfonyl groups, are in turn made from fluorinated polymers which have pendant side chains containing sulfonyl halide groups by reduction with, for example, hydrazine.  Fluorinated ion exchange polymers which have pendant side chains containing -OCF2COOR groups and also pendant side chains which contain sulfonyl groups can also be made by copolymerization of a mixture of monomers, one of which is a vinyl monomer which contains the indicated carboxylic group; and also by treatment of a polymer which contains -OCF2CF2SO3H or salts thereof with a combination of fluorine and oxygen.
