An 8-bit 19 MS/s low-power 0.35 μm CMOS pipelined ADC for DVB-H

This paper proposes an 8b 19 MHz CMOS pipelined analog-to-digital converter (ADC) for DVB-H. In order to reduce the power consumption a combination of techniques has been used, such as op-amp sharing, low-power amplifiers with gain boosting and an aggressive capacitor scaling. The prototype ADC fabricated in 0.35 μm CMOS demonstrates a maximum differential nonlinearity (DNL) of 0.63 least significant bit (LSB) and a maximum integral nonlinearity (INL) of 0.58 LSB with a peak signal-to-noise-and-distortion ratio (SNDR) and spurious-free dynamic range (SFDR) of 42.76 and 51.57 dB at 19 MHz. The ADC with an active area of 4.78 mm2 consumes less than 4 mW at the mentioned sampling frequency.

► In this paper we present an 8b 19 MHz CMOS pipelined analog-to-digital converter for DVB-H applications. ► A combination of different power saving techniques leads to a very low power solution, less than 4 mW. ► Some of the proposed techniques, such as quasi-floating-gate switch, supposes a novelty in pipelined ADC implementation.
