Abstract:
This invention discloses a multiplying digital-to-analog converter (MDAC) applied to a pipelined analog-to-digital converter (pipelined ADC). The MDAC includes an operational amplifier. The MDAC samples a differential input signal in a sampling phase and performs subtraction and multiplication operations in an amplification phase according to a first reference voltage and a second reference voltage. The common-mode voltage of the first reference voltage and the second reference voltage is not substantially equal to the common-mode voltage of the differential input signal; and/or the voltage difference between the first reference voltage and the second reference voltage is not substantially equal to one half of an allowed maximum peak-to-peak value of the differential input signal. One of the first reference voltage and the second reference voltage can be ground.

Claim (Index 5):
The MDAC of  claim 1  further comprising:\n a fifth capacitor having a ninth end and a tenth end, wherein the ninth end is coupled to the first reference voltage in the sampling phase and coupled to the first input terminal of the operational amplifier but not to the first reference voltage in the amplification phase, wherein the tenth end receives the differential input signal in the sampling phase and is coupled to a common-mode voltage of the second reference voltage and the third reference voltage in the amplification phase; and \n a sixth capacitor having an eleventh end and a twelfth end, wherein the eleventh end is coupled to the first reference voltage in the sampling phase, and is coupled to the second input terminal of the operational amplifier but not to the first reference voltage in the amplification phase, wherein the twelfth end receives the differential input signal in the sampling phase and is coupled to the common-mode voltage in the amplification phase.
