Thermal noise has been a fundamental bottleneck in building high dynamic range switched capacitor (SC) circuits. This brief proposes an SC thermal-noise-canceling circuit. The technique, demonstrated using a unity-gain sample-and-hold amplifier (SHA) in IBM 32-nm silicon-on-insulator (SOI) process, gives 5.0-, 4.4-, and 3.7-dB improvements while operating at 100, 250, and 500 MHz, respectively, and consuming only 30% additional power as compared to 400% to get a similar improvement without noise cancelation.
