Multiplication circuit with serially connected capacitive couplings |
摘要 |
A multiplication circuit includes a plurality of switches which receive a common analog input voltage and a reference voltage and which alternatively output the input voltage or the reference voltage. A first capacitive coupling is provided which has a plurality of capacitors, each of which receives an output from a respective switch, and a second capacitive coupling is provided with a plurality of capacitors, each of which likewise receives an output from a respective switch. One or more of the capacitors in the first capacitive coupling is connected to the second capacitive coupling. A first inverted amplifier and a second inverted amplifier are connected in series to the output of the second capacitive coupling with individual feedback.
