| dc.description.abstract | In this paper, a bootstrapping technique is applied to a bulk-driven voltage buffer for canceling the gate-source transconductance in order to improve the cell gain, the linearity and reduce the input-referred noise. The bootstrapped circuitry is conveniently implemented by only using a capacitor and a pseudo resistor. The suitability of the technique is demonstrated by simulation results using a flipped voltage follower, even though it is general and can be applied to other structures. A 1-V buffer is designed in 0.18 µm CMOS technology, showing a 4.3 times improvement in the voltage gain (conventional 0.21 V/V, bootstrapped 0.90 V/V), increasing 5 times the input voltage range for a 1% THD (conventional 50 mV, bootstrapped 250 mV) and reducing the input equivalent noise around a 16% (conventional 180 nV/-√Hz, bootstrapped 155 nV/√Hz at 10 kHz). | en |
