Patent number: 8963622Abstract: High voltage rated isolation capacitors of inductors are formed on a face of a primary integrated circuit die. The isolation capacitors or inductors AC couple the primary integrated circuit in a first voltage domain to a second integrated circuit in a second voltage domain. The isolation capacitors or inductors DC isolate the primary integrated circuit from the second integrated circuit die. Isolated power transfer from the first voltage domain to the second voltage domain is provided through the high voltage rated isolation capacitors or inductors with an AC oscillator or PWM generator. The AC oscillator voltage amplitude may be increased for an increase in power through the high voltage rated isolation capacitors or inductors.Type: GrantFiled: March 7, 2014Date of Patent: February 24, 2015Assignee: Microchip Technology IncorporatedInventors: Thomas Youbok Lee, Rudy Jaramillo, Patrick Kelly Richards, Lee Furey

Patent number: 6700931Abstract: A radio frequency identification (RFID) tag device having a pulse position modulation (PPM) decoder circuit which calculates a relative frequency relationship between an internal clock-oscillator of the RFID tag device and an external PPM source such as a RFID tag reader, and then synchronizes the RFID tag device PPM decoder circuit to the required precision for reliable PPM symbol decoding. The PPM decoder is synchronized by measuring the “counts per pulse” (CPP) from a calibration cycle having a plurality of pulses in a single symbol frame.Type: GrantFiled: July 6, 2000Date of Patent: March 2, 2004Assignee: Microchip Technology IncorporatedInventors: Youbok Lee, Lee Furey, Sam Alexander, William F.

Patent number: 6496113Abstract: A radio frequency identification (RFID) tag on a single layer substrate comprises a semiconductor integrated circuit RFID tag device and antenna circuit. A connection jumper may be used to bridge over the antenna circuit coil turns. The RFID tag device is located on the same side as an inductor coil and capacitor which forms a parallel resonant antenna circuit. The inductor coil has an inner end and an outer end. The inner or outer end may be connected directly to the RFID tag device and the outer or inner end be may connected to the RFID tag device with a jumper over the inductor coil turns, or the RFID tag device may bridge the inductor coil turns when being connected to both the inner and outer ends. An encapsulation (glop top) may be used to seal the RFID tag device and jumper, and an insulated coating may be used to cover the entire surface of the substrate to create an inexpensive “chip-on-tag.Type: GrantFiled: August 10, 2001Date of Patent: December 17, 2002Assignee: Microchip Technology IncorporatedInventors: Youbok Lee, Lee Furey, Roger St. Amand
