Abstract:
1. An integrated circuit chip comprising: a first single-ended-to-differential amplifier configured to generate a differential output associated with an input of said first single-ended-to-differential amplifier; a second single-ended-to-differential amplifier arranged in parallel with said first single-ended-to-differential amplifier, wherein said second single-ended-to-differential amplifier is configured to generate a differential output associated with an input of said second single-ended-to-differential amplifier; a first set of switch circuits arranged downstream of said first single-ended-to-differential amplifier, wherein one of said switch circuits in said first set comprises a differential input associated with said differential output of said first single-ended-to-differential amplifier; a second set of switch circuits arranged downstream of said second single-ended-to-differential amplifier, wherein one of said switch circuits in said second set comprises a differential input associated with said differential output of said second single-ended-to-differential amplifier; and a first differential-to-single-ended amplifier arranged downstream of a first one of said switch circuits in said first set and downstream of a first one of said switch circuits in said second set, wherein said first differential-to-single-ended amplifier comprises a differential input associated with a differential output of said first one of said switch circuits in said first set.
