Abstract:
A driver circuit, comprising:an input stage coupled for receiving an input signal and coupled to provide first and second drive signals, wherein the input stage comprises: a first input transistor having a control input coupled to receive the input signal, a first conductor coupled to a second power supply conductor and a second conductor coupled to provide the first drive signal; and a first current mirror circuit having an input coupled to receive a first reference signal and having an output coupled to provide the second drive signal when the input signal is above the first reference signal; and an output stage coupled between first and second power supply conductors and having an output node, the output stage including, (a) a first transistor having a first conduction terminal coupled directly to the first power supply conductor, a second conduction terminal coupled directly to the output node, and a control terminal coupled to receive the first drive signal; and (b) a second transistor having a first conduction terminal coupled directly to the first power supply conductor, a second conduction terminal coupled directly to the output node, and a control terminal coupled to receive the second drive signal.
