ABSTRACT:
Because of variations in open loop gain and bandwidth in successive approximate register (SAR) analog-to-digital converters (ADCs), designing amplifiers with the desired characteristics is difficult. Here, a multipath amplifier is provided that accounts for the variations in open loop gain and bandwidth. Preferably, a number of cascaded amplifiers are provided that can auto-zero to account for offset voltages so as to allow the multipath amplifier to be stable over the desired open loop gains and bandwidths.
