ABSTRACT:
Buffer amplifiers are provided that demonstrate enhanced efficiency because they include current sources which are configured to be switched off during operational modes in which the amplifiers' output signals are not needed. Amplifier embodiments include charge-transfer transistors and filter capacitors that reduce spurious signals which may be generated by the switching operations.
