Abstract: First, second input terminals of a sense amplifier are coupled to first, second memory sensing nodes. A first input transistor has a channel arranged between a first comparator input and a first comparator output, and a control terminal at a bias node. A second input transistor has a channel arranged between a second comparator input and a second comparator output, and a control terminal at a bias node. The first and second comparator inputs are selectively couplable to each other, in response to compensation signal assertion, or to the first and second input terminals, in response to compensation signal de-assertion. The bias node is selectively couplable to a comparator biasing node in response to bias enable assertion, or is floating in response to the bias enable de-assertion. A sensing circuit produces a read signal as a function of a difference between first, second currents at the comparator outputs.

Abstract: A bidirectional PFC system includes a high-frequency branch with a first transistor connected between an IO node and a high-frequency tap, and a second transistor connected between the high-frequency tap and a reference node, and a low-frequency branch with a first thyristor connected between the IO node and a low-frequency tap, and a second thyristor connected between the low-frequency tap and the reference node. An inductor is connected between the first node and the high-frequency tap. A first capacitor is connected between the first node and the low-frequency tap. The first node and the low-frequency tap are coupled to input terminals. A control circuit generates first and second gate drive signals for the transistors so as to modify an AC signal at the input terminals such that the AC current falls below a holding current of the second thyristor prior to zero crossing of the AC voltage.

A first circuit controls assertion of the first signal for a first fixed time period when the second binary signal is asserted.
