20090189688 - High dynamic range ask demodulator for use in an rfid transponder: An ASK demodulator for use in an RFID transponder having a limiter circuit associated with the antenna circuit and converting the ASK antenna fieldstrength modulation into an ASK limiter current modulation by limiting the antenna voltage to a fixed value and thereby causing the limiter current to be substantially proportional... Agent: Texas Instruments Incorporated

20090174471 - Samples of bandlimited signals recovery system and method: A method and system of sample recovery is disclosed. In one embodiment, a method includes selecting initially in an arbitrary manner, a current symbol from a sequence of input samples, comparing a symbol timing estimate associated with the current symbol to a predetermined threshold, selecting a future symbol strobe that...
