|---|---|---|
A 10-bit 30-MS/s successive approximation register analog-to-digital converter (ADC), which is suitable for low-power sub-sampling applications, is presented. Bootstrapped switches are used to enhance the sampling linearity at the high input frequency. The proposed ADC adopts a binary-weighted split-capacitor array with the energy efficient switching procedure and includes an asynchronous clock scheme to yield more power and speed-efficiency. The ADC is fabricated in a 65nm complementary metal-oxide-semiconductor technology and occupies an active area of 0.07mm^2. The differential and integral nonlinearities of the ADC are less than 0.82 and 1.13 LSB, respectively. The ADC shows a signal-to-noise-distortion ratio of 56.60dB, a spurious free dynamic range of 73.35dB, and an effective number of bits (ENOB) of 9.11-bits with a 2.5-MHz sinusoidal input at 30-MS/s. It exhibits higher than 8.86 ENOB for input frequencies up to 78-MHz. The ADC consumes 0.85mW at a 1.1V supply and achieves a figure-of-merit of 51fJ/conversion-step. |
