Patent number: 8897467Abstract: An electronic amplifier for driving a capacitive load may include first and second differential input terminals to receive an input signal, and first and second differential output terminals to provide a differential output signal. The amplifier may further include a first operational device having first and second differential inputs connected to the first and second differential input terminals, respectively, and an output connected to the first differential output terminal, and a second operational device having first and second differential inputs connected to the first and second differential input terminals, respectively, and an output connected to the second differential output terminal. The first and second operational devices may be operatively configured so that both the first and the second output terminals are at a same reference potential during periods in which a magnitude of differential output signal amplitude decreases.Type: GrantFiled: December 22, 2010Date of Patent: November 25, 2014Assignee: STMicroelectronics Design and Application S.R.O.Inventors: Peter Murin, Tomas Folk, Pavel Panus

Patent number: 7825734Abstract: An amplifier with an output protection having an input stage defining a feedback node, an output stage connected to the feedback node and defining an output node supplying an output voltage, and a feedback stage connected between the output and the feedback nodes. A mirror stage is connected to the feedback node and has the same structure as the output stage, the mirror stage defining a reference node connected to the feedback stage for generating a reference voltage to be compared to the output voltage by the feedback stage. The feedback stage generates a current limitation signal fed to the feedback node when a difference between the output and the reference voltages is higher than a threshold.Type: GrantFiled: April 4, 2008Date of Patent: November 2, 2010Assignee: STMicroelectronics Design and Application s.r.o.Inventors: Peter Murin, Hynek Saman
