Abstract:
1. A circuit, comprising: a differentiator configured to receive a first electrical signal which is a time-variable signal and supply a second electrical signal that is a time derivative of said first electrical signal; a transconductance amplifier configured to receive the second electrical signal and generate a third electrical signal that is a function of the second electrical signal and is amplified with respect to the second electrical signal; a power supply network for the differentiator and transconductance amplifier configured to supply respective power supply signals to the differentiator and transconductance amplifier; and a driving circuit of the power supply network, configured to drive the power supply signals in response to one or more biasing signals; said third electrical signal being, at least in part, supplied to said driving circuit for use in driving the power supply network so as to modulate an amplitude of at least one of the power supply signals.
