A low voltage-power 13-bit 16 MSPS CMOS pipelined ADC

A low voltage-power, 13-bit and 16 MSPS analog-to-digital converter (ADC) was implemented in 0.25-/spl mu/m one-poly five-metal standard CMOS process with MIM capacitors. This ADC used a constant-gm switch to improve the nonlinear effect and a telescopic operational transconductance amplifier with a wide-swing biasing technique for power saving and low supply voltage operation. The converter achieved a peak SNDR of 59.2 dB with 16.384 MSPS, a low supply voltage of 1.3V, and Nyquist input frequency of 8.75 MHz. The static INL of /spl plusmn/2.0 LSB and DNL of /spl plusmn/0.5 LSB were obtained. The total power consumption of this converter was 78 mW. This chip occupied 3.4 mm /spl times/ 3.6 mm area.
