Source Type

A circuit comprises a successive approximation analog-to-digital converter that comprises a feedback path and is operated for example in accordance with the successive approximation method. The feedback path is configured to translate a digital signal in accordance with a prescribed function and to furthermore convert the translated digital signal into an analog feedback signal. For example, the prescribed function can be an exponential function. As such, it can be possible to convert an input signal into an output signal by means of a nonlinear characteristic.

First transistor logic is arranged by a first logic provider in circuit form and provides a minimum of functionality of the semiconductor device employed to bring up the semiconductor device, wherein the minimum of functionality is encrypted using a first encryption key. Second transistor logic is arranged by a second logic provider, different than the first logic provider, in circuit form to include security keys capable to perform cryptographic capabilities using a second encryption key. The second transistor logic further includes functionality that completes the semiconductor device as a chip device and is ready to process secure communication signals.

According to one embodiment, a connection is established between a first communication device and a second communication device in accordance with one or more communication layers. Each communication layer is associated with a standard structure and protocol. An ad hoc communication layer structure and/or protocol are determined at the first communication device. The ad hoc communication layer structure and/or protocol are communicated to the second communication device. One or more of the standard structures and/or protocols are replaced at the first communication device with the ad hoc communication layer structure and/or protocol responsive to the second communication device acknowledging acceptance of the ad hoc communication layer structure and/or protocol.

A sequence of symbols is received on a first channel. A noise contribution of a given synchronization symbol is estimated; a reference noise contribution of at least one further symbol is estimated. Based on the noise contribution and further based on the reference noise contribution the given synchronization symbol is selectively considered when determining a coupling coefficient of crosstalk between the first channel and a second channel.

Devices are provided including an SFP interface and a further interface for wire-based data transmission. A conversion circuit converts between SFP interface signals and wire-based interface signals. The interfaces and the conversion circuit may be, but need not be, provided on a same circuit board.


Communication in a first spectrum and via a first transmission line (151) of first data (131) is according to a time-division duplexing scheme (171) such as G.fast. Communication in a second spectrum and via a second transmission line (152) of second data (132) is according to a frequency-division duplexing scheme (172) such as VDSL2. The first and second spectra both comprise an overlap spectrum. The first transmission line (151) experiences first crosstalk (161) from the second transmission line (152) and the second transmission line (152) experiences second crosstalk (162) from the first transmission line (151).

A sequence (200) of symbols (201-1 - 201-3, 202-1 - 202-14) is received on a first channel. A noise contribution of a given synchronization symbol (201-2) is estimated; a reference noise contribution of at least one further symbol (201-1, 201-3, 202-1 - 202-14) is estimated. Based on the noise contribution and further based on the reference noise contribution the given synchronization symbol (201-2) is selectively considered when determining a coupling coefficient of crosstalk between the first channel and a second channel.
