Abstract :
A 25-GHz complementary metal oxide semiconductor (CMOS) cascaded single-stage distributed amplifier (CSSDA) using standard 0.18-μm CMOS technology is presented in this letter. It demonstrates the highest gain-bandwidth product (GBP) with smallest chip area reported for a fully-integrated CMOS wideband amplifier using a standard Si-based integrated circuit process. The chip size including testing pads is only 0.36mm2, and the ratio of GBP to chip size achieves 552GHz/mm2. This circuit is the first CSSDA realized in CMOS technology, and represents state-of-the-art performances.
