Versatile dual-mode class-AB CMOS four-quadrant analog multiplier circuit is presented. The dual translinear loops and current mirrors are the basic building blocks in realization scheme. This technique provides; wide dynamic range, wide-bandwidth response and low power consumption. The major advantages of this approach are; its has single ended inputs; since its input is dual translinear loop ...

A new mismatch insensitive 1.5-bit multiplying digital–analogue converter (MDAC) is proposed. This circuit samples the input in closed-loop form using the opamp in non-inverting configuration; hence, only the parasitic input capacitance loads the previous stage. This technique uses a fully-differential four-input OTA instead of two single-ended two-input OTAs to further improve power consumptio...

We measured cerebral activation with functional magnetic resonance imaging at 3 Tesla while eight healthy volunteers performed various number processing tasks known to be dissociable in brain-lesioned patients: naming, comparing, multiplying, or subtracting single digits. The results revealed the activation of a circuit comprising bilateral intraparietal, prefrontal, and anterior cingulate comp...

This paper proposes the high-frequency mathematical model for common-mode noise voltage of a DC–DC buck converter. The equivalent circuit considering parasitic impedance is proposed, and then path analyzed using this circuit. source generated by switching device divided into trapezoidal ringing sources mathematically modeled. For high accuracy at high-frequency, including difference between ris...
