Patent number: 7642983Abstract: An automatic tuning procedure can be used to allow a small, high efficiency ferrite antenna assembly to be used in various FM frequency based devices. The ferrite antenna can take the form of a rod or flat disk, for example, which can use a pick-up coil and tuning coil to provide sufficient signal strength using a small FM antenna. A balanced amplifier can be used to provide differential input in order to further reduce noise. A microcontroller can determine the strength of the FM signal at various frequencies and can automatically tune the operating frequency to optimize system performance.Type: GrantFiled: January 26, 2007Date of Patent: January 5, 2010Assignee: PowerQ Technologies, Inc.Inventor: Steven Jay Davis

Patent number: 6859102Abstract: Embodiments of the present invention include an amplification system and method of controlling an amplifier. The method comprises receiving a first digital signal representing a desired amplifier signal level, receiving a portion of said amplifiers output signal, and adjusting the voltage on a body terminal of said amplifier so that the output signal is maintained in a predetermined range. The amplification system comprises an MOS amplifier wherein the body terminal is adjusted to maintain the output at desired levels. In one embodiment, the body terminal is a fine adjust, and an input attenuator is used for a coarse adjust. In another embodiment, input and output couplers are coupled to the amplifier, and portions of the input and output signals are used to adjust the body terminal to maintain a desired output level.Type: GrantFiled: September 26, 2002Date of Patent: February 22, 2005Assignee: PowerQ Technologies, Inc.Inventor: Larry Martin Tichauer

Patent number: 6784744Abstract: Embodiments of the present invention provide an amplifier circuit and method that can be used to save power or reduce distortion in an electronic system, such as a wireless communication system. In one embodiment, the present invention includes an amplifier circuit comprising a transistor having a gate terminal, drain terminal, body terminal, and a load. An input signal has different signal envelopes during different time periods. A control signal coupled to the body terminal is used to change the voltage on the body terminal when the input receives different envelopes. Accordingly, the amplifier can be biased to use less power when lower envelopes are being received. Electronic systems, such as wireless communication systems, can realize advantageous performance enhancements by utilizing the amplifier and other techniques employed by embodiments of the present invention.Type: GrantFiled: September 26, 2002Date of Patent: August 31, 2004Assignee: PowerQ Technologies, Inc.Inventor: Larry Martin Tichauer
