Patent number: 8265198Abstract: A signal processing circuit including a demodulator having an input for receiving a received signal which includes falling and rising signal edges, and an output for outputting a demodulated received signal which, with signal edges of the received signal, includes transitions from a first level to a second level or vice versa, wherein times of the transitions depend on steepnesses of the signal edges. Additionally, the circuit includes a signal generator having an input for receiving the demodulated received signal and coupled to the output of the demodulator, and an output for outputting a corrected demodulated received signal which includes transitions, the times of which relative to the times of the transitions of the demodulated received signal are set based on a reference signal to reduce influences of the steepnesses of the falling and rising signal edges in the corrected demodulated received signal relative to the demodulated received signal.Type: GrantFiled: October 12, 2006Date of Patent: September 11, 2012Assignee: Infineon Technologies AGInventors: Thomas Leutgeb, Helmut Koroschetz
