Sometimes, there are too many choices in this world. My benchtop function generator can output a sine, square, or saw wave ...

A low-power switched-capacitor third-order sigma- delta (ΣΔ) modulator suitable for portable sensor systems is described. The architecture uses only one operational amplifier working in a ...

The OP-Amp with the proposed circuit shows the systematic offset voltages less than 100 /spl mu/V in whole operating ranges. Furthermore, the random offsets also can be compensated by the proposed ...
