A 12-bit video speed pipelined switched capacitor analog-to-digital co
nverter (ADC) has been implemented in a 0.5 mu m standard CMOS process
. It operates from a single 2.6-3.3V supply, dissipates 23mA (independ
ent of supply voltage) at 20 MSPS and occupies only 1.1mm(2). A 61dB S
INAD (f(in) = 4.5 MHz) and an effective resolution bandwidth of 9 MHz
is achieved.
