Kind Code:
B2
Abstract:
PCT No. PCT/EP93/03051 Sec. 371 Date Jul. 20, 1995 Sec. 102(e) Date Jul. 20, 1995 PCT Filed Nov. 2, 1993 PCT Pub. No. WO94/11951 PCT Pub. Date May 26, 1994An interstage amplifier for a pipelined analog to digital converter comprises an operational amplifier (50) having a first pair of capacitors (55,58), a second pair of capacitors (56,57), and switching means (59-62) connected to the capacitors and amplifier. The switching means interchanges the capacitor connections to compensate for offset in the amplifier. The arrangement provides first-order correction of capacitor mismatch.
