Abstract:
A source driver comprising a first DAC with a positive polarity (PDAC), a second DAC with a negative polarity (NDAC), first and second operational amplifiers. Each operational amplifier is characterized with a 1st & 2nd stage and an output stage. The PDAC and NDAC are coupled to the first and second operational amplifiers through a first pair of switches. The 1st & 2nd and output stages of the first operational amplifier are coupled to the 1st & 2nd and output stages of the second operational amplifier through a second pair of switches. The first and second operational amplifiers are coupled to odd data lines and even data line through a third pair of switches.
