Abstract:
A differentiator generates a time derivative signal from a time-variable signal. A transconductance amplifier generates a biasing control signal as a function of the time derivative signal. A supply network functions to supply the differentiator and transconductance amplifier. The supply network is driven by the biasing control signal output from the transconductance amplifier. With this configuration, speed of operation of the differentiator and transconductance amplifier vary with the supply provided by the supply network, and the supply is modulated as a function of the received time-variable signal.
