This letter proposes a mismatch insensitive switchedcapacitor multiply-by-four (4X) amplifier using the voltage addition scheme. The proposed circuit provides 2-times faster speed and about half of silicon area when compared with the cascade of conventional 2X amplifiers. Monte-Carlo simulation results show about 15% gain accuracy improvement over the cascaded 2X- amplifiers.
