“…It has to perform a near-perfect, i.e., low-loss noise-free linear transfer of the signal samples. With the arrival of bucket-brigade technology, however, a switched capacitor circuit can be implemented as a monolithic integrated circuit using bipolar, MOS [l], or JFET [2] switches, and because the storage capacitors are referenced to a switching potential rather than fixed reference level, the transfer operation can be accomplished very efficiently (typically as low as 0.01-percent loss per transfer has been reported for clock rates below 10 MHz) by a simple onetransistor switch.…”
