Abstract

This paper describes a new programmable gain amplifier (PGA) for data acquisition systems. Its small size, low voltage capability and versatility make it ideally suited for high volume integration. A new DC-offset technique is introduced to achieve 0V compliant operation without the need of switched capacitor techniques. Offset cancellation is achieved on a system level in the digital domain, greatly reducing complexity. A new low-power bias current generator is introduced, capable of generating accurate temperature compensated currents with minimum complexity
