Embodiment Construction

[0016] Before the following detailed description of the exemplary embodiments with reference to the drawings, it should be noted that identical or functionally identical elements have the same reference numerals, and a repeated description of these elements is omitted. The descriptions of elements with the same reference numbers are therefore interchangeable.

[0017] figure 1 A block diagram of a current-to-voltage converter 100 according to one embodiment is shown. A current-to-voltage converter 100 for providing a voltage signal 102 based on a current signal 101 has a first active stage 103 comprising an input 104 and an output 105 . The input 104 of the first active stage 103 may also be referred to as an input node 104 . Furthermore, the current-voltage converter 100 has a second active stage 106 coupled between the output 105 of the first active stage 103 and the input 104 of the first active stage 103 .

[0018] The first active stage 103 is designed to receive a cur...

Abstract

A current-to-voltage converter for providing a voltage signal based on a current signal has a first active stage having an input and an output. The first active stage is configured to receive the current signal at its input and provide the voltage signal at its output. In addition, the current-to-voltage converter has a second active stage that is coupled between the output of the first active stage and the input of the first active stage. The second active stage is configured to provide the input of the first active stage with a feedback signal that frequency-selectively counteracts amplification, by the first active stage, of signal components of a current signal applied to the input of the first active stage that have a frequency outside of a prescribed useful frequency band.

Description

technical field [0001] Embodiments of the invention include a current-to-voltage converter that may be used, for example, in a receiver of a mobile phone. Other embodiments include receivers such as may be used in mobile radiotelephones. Other embodiments include methods of providing a voltage signal based on a current signal. Other embodiments include methods for receiving received signals, eg mobile radio signals. Background technique [0002] Some mobile phone standards require simultaneous transmission and reception (so-called full-duplex). In this case, the duplexer typically significantly reduces the transmit signal on the receiver input (TX-signal, TX=transmit), but there is a strong signal on the receiver input (RX-in, RX=receive) , which are mixed to baseband in the receive mixer (RX mixer) and attenuated or in some cases even have to be attenuated by filtering before the analog-to-digital converter (ADC). In other words, it is difficult in some cases to deal wi...
