Abstract:
The voltage applied to the gate terminals of the charging transistors and charge-transfer transistors of two parallel pumping branches forming a charge pump is a boosted voltage generated internally and supplied in a crosswise manner. In particular, for driving the charge pump, first and second driving signals are generated respectively for the first and for the second pumping branch via a first and respectively a second driving circuit; the first and second driving signals are also supplied respectively to a first and to a second auxiliary charge pump to obtain respectively first and second voltage-boosted signals; and the first and second boosted voltages are respectively supplied to the second and to the first driving circuit.
Abstract:
A parallel sense amplifier includes a measuring branch for receiving an input current to be measured, a plurality of reference branches each one for receiving a reference current, and a plurality of comparators each one for comparing a voltage at a measuring node along the measuring branch with a voltage at a reference node along a corresponding reference branch; the amplifier further includes a multiple current mirror for mirroring the input current into each reference branch.
