Analog circuit

An analog circuit comprising:

• a plurality of analog functions, which are divided into at least two groups of analog functions;
• and
• an interconnection structure configured to interconnect the plurality of analog functions so as to enable transfer of both voltage and current signals between analog functions among the plurality of analog functions, wherein
• the interconnection structure comprises at least two hierarchy levels of interconnections, wherein
• a local-bus hierarchy level is configured to interconnect analog functions of a respective group, and
• a global-bus hierarchy level is configured to interconnect analog functions of the plurality of groups,
• the local-bus hierarchy level comprises voltage signal lines for transferring voltage signals and/or current signal lines for transferring current signals, and
• the global-bus hierarchy level comprises voltage signal lines for transferring voltage signals and/or current signal lines for transferring current signals, wherein
• the local-bus hierarchy level comprises, for at least one group, at least
• a first local bus, which is configured to interconnect a set of analog functions of the respective group, and
• a second local bus, which is configured to interconnect another set of analog functions of the respective group, wherein
• the first local bus comprises voltage signal lines for transferring voltage signals,
• the second local bus comprises current signal lines for transferring current signals, and
• the interconnection structure comprises at least a further hierarchy level of interconnections, wherein
• at least one intermediate-bus hierarchy level is configured to interconnect analog functions of a set of groups among the plurality of groups, and
• the at least one intermediate-bus hierarchy level comprises voltage signal lines for transferring voltage signals and/or current signal lines for transferring current signals.
