Title: Wideband voltage controlled oscillator with good noise immunity
Inventor: SEE PUAY HOE
IPC: H03B5/12
Filed: 2000-08-31
Abstract: A Voltage Controlled Oscillator (VCO) with the ability to tune its operating frequency over a wide range using a limited control voltage range. The VCO implements a novel resonant circuit that provides the wide frequency tuning range and simultaneously provides increased immunity to induced low frequency noise. The resonant circuit utilizes an element configuration that includes high pass filters (402, 422 and 404, 424) on each input to the resonant circuit. Varactor diodes (432, 434) are used to couple a conventional tuning circuit to the remainder of the resonant circuit.

Next, the first digital modem (26a) establishes a connection with a second digital modem (26b). Segments of the controller (24) may be co-located or located in different locations and connected through either Internet or PSTN. Then, the second digital modem (26b) dials up the second analog modem (12b) under direction of the controller (24). Subsequently, the controller (24) commands the digital modems to establish a connection at the fastest possible symmetric rate, near-symmetric, or any other pre-configured rate.
