Patent number: 8644776Abstract: A power detection system is disclosed that determines a power level of a transmission signal. The power detection system includes an adjustable comparator circuit, an algorithmic state machine, and an output node. The adjustable comparator circuit receives the transmission signal and provides an adjusted transmission signal, and further compares the adjusted transmission signal to a reference signal. The algorithmic state machine iteratively adjusts the adjustable comparator circuit until the adjusted transmission signal is substantially close to the reference signal. The output node is coupled to the algorithmic state machine and provides an output signal that is responsive to the power level of the transmission signal and to the reference signal.Type: GrantFiled: August 25, 2008Date of Patent: February 4, 2014Assignee: Peregrine Semiconductor CorporationInventors: Dan Nobbe, Robert Broughton, Tero Ranta, James Swonger, R.

Patent number: 8022734Abstract: A power detection system is disclosed that includes a detector circuit and a comparator circuit. The detector circuit includes a first transistor, a second transistor that is not identical to the first transistor, and a third transistor that is substantially identical to the first transistor. Each of the transistors is commonly coupled to a current source and is coupled to a differential input voltage. The comparator circuit is for providing an output that is representative of whether the input voltage is above or below a threshold voltage responsive to a difference between the first transistor and the second transistor.Type: GrantFiled: August 25, 2008Date of Patent: September 20, 2011Assignee: Peregrine Semiconductor CorporationInventor: Robert Broughton

Patent number: 7795968Abstract: An RF PA operable in two or more selectable power ranges is disclosed. Switches configure the circuit for each range such that an amplifier device corresponding to the range provides final amplification, and all lower power amplifier devices also amplify the signal. An exemplary design includes a low power amplifier configurable for operation solo, or in parallel with a medium power amplifier, to deliver an appropriately matched signal either directly to the RF PA output, or first to the input of a high power amplifier for the highest power range. The signal in all ranges of the exemplary design is conditioned in part by the matching circuitry disposed between the high power amplifier and the RF PA output, which traverses no switches in high power range operation. The entire RF PA, including switches, control and matching circuitry, is fabricated on a single monolithic integrated circuit, an achievement may be facilitated by UTSI CMOS processing.Type: GrantFiled: January 12, 2009Date of Patent: September 14, 2010Assignee: Peregrine Semiconductor CorporationInventors: Yang Li, Robert Broughton, James Bonkowski, Peter Bacon
