Abstract
An analog circuit (1) including: a signal input (VSIG) to provide an input signal via capacitive coupling, an edge detection stage (10) operable to detect rising and falling edges of the input signal provided at the signal input (VSIG), an amplifier stage with continuously variable gain and bandwidth (30) between the signal input (VSIG) and the edge detection stage (10) and operable to amplify the input signal provided by the signal input (VSIG).
