Abstract
A second-order double-sampled &Sgr;&Dgr; analog/digital converter uses two fully differential switched-capacitor integrators coupled in cascade. The first integrator has a fully-floating double-sampled, bilinear switched capacitor input structure. The second integrator has a double-sampled lossless discrete integrator (LDI) switched-capacitor input structure. The converter achieves an excellent SNR with a reduced number of switches for low power consumption.
