Abstract :
Folding and interpolating converters offer the speed of flash type devices but at a fraction of the area and power consumption. The performance of bipolar based folding converters has come to rival that of other topologies. This work describes a folding architecture that is compatible with digital CMOS. For speed, the analog circuitry is fully-differential continuous-time current-mode and open loop. This folding architecture is implemented in 6 bit and 8 bit ADCs functioning at 3.3 V.
