HIGH PERFORMANCE RECONFIGURABLE VOLTAGE BUFFERS

摘要

In this disclosure, new structures for high-performance voltage buffers (source followers and emitter followers) are described. The structures achieve high performance (linearity) and reduce power consumption. In addition, they are reconfigurable to optimize the performance and power consumption depending on the input frequency range.

1. A voltage buffer having a voltage input node and a voltage output node, the voltage buffer comprising:
a source follower device having a first terminal connected to the voltage input node and a second terminal connected to the voltage output node; a cascode current source device connected to the second terminal of the source follower device; and a bootstrap device configured to control the variation of the voltage across the third terminal and the second terminal of the source follower device.
