Abstract
A compact high-frequency CMOS analog buffer for testing purposes is presented. A prototype integrated in a 3-μm CMOS process drives a 15-pF 10-kΩ load, and shows a bandwidth of more than 30 MHz, a large-signal time to 1% less than 90 ns, and a dynamic range of over 77 dB; power consumption is 2.4 mA per cell. Its small size (less than 0.18 mm2) makes it suitable for monitoring low-capacitance internal nodes of analog or mixed-mode VLSI circuits
