Embodiment Construction

[0036] exist figure 1 A block diagram relating to an embodiment according to the present invention is shown in .

[0037] The receiving unit 11 receives an input signal s. The input signal s comprises a first signal s1 having a first signal magnitude and a second signal s2 having a second signal magnitude. In this embodiment, the first signal s1 is a UHF-RFID signal at a first carrier frequency f1 of about 865 MHz. The second signal s2 is a GSM signal at a second carrier frequency f2 of about 915 MHz. The input unit 11 forwards the input signal s to a first non-linear component 18 , here a voltage multiplier (SV) 18 .

[0038] The voltage multiplier 18 is constructed similarly to a charge pump and includes an interconnection of diodes and capacitors. The first voltage multiplier 18 has the function of an electronic mixer due to its non-linear characteristic curve. The first voltage multiplier 18 generates a baseband sum signal 21a from the input signal s. The first volta...

Abstract

The invention relates to a method and a circuit for matching a first reference value for generating a first bit stream (20) from an input signal (s) by a first amplitude matching unit (12). The input signal (s) includes first and second signals (s1, s2). The first signal (s1) and the second signal (s2) form a baseband sum signal (21a). The first non-linear component (18) demodulates the input signal (s) and outputs the demodulated input signal (s). The amplitude matching unit (12) outputs a first bit stream (20) from the demodulated input signal (s) based on the first reference value. The reference value matching unit (19) includes a detection unit (191) that detects the first and second signals (s1, s2). When removing the first and second signals (s1, s2), the adjustment unit (192) adjusts the first reference value to the basic reference value.

Description

technical field [0001] The invention relates to a method and a circuit for matching a first reference value for generating a first bit stream from an input signal by a first amplitude matching unit. [0002] In particular, the invention relates to a method for adapting a first reference value. The first reference value is used to generate the first bit stream according to the input signal of the amplitude matching unit. The input signal includes a first signal and a second signal. The first signal has a first signal magnitude and the second signal has a second signal magnitude. The first signal magnitude and the second signal magnitude form a mixed magnitude. The first nonlinear part demodulates the input signal and outputs the demodulated input signal as a mixed signal. The amplitude matching unit outputs a first bit stream from the mixed signal or the demodulated input signal based on the first reference value. [0003] In particular, the invention also relates to a cir...
