Abstract
With the purpose of realizing an amplifier capable to process large dynamic range signals, a programmable gain range amplifier that comprises of attenuator, variable gain amplifier, differential amplifier is developed. This amplifier has a programmable gain from -20 dB to 33 dB and a DC to 700 MHz bandwidth. Besides, remote programmability makes this amplifier convenient to use. To test its feature in signal conditioning, a BaF2 detector signal is amplified and results show good performance. This amplifier has promising application possibility in high-speed large dynamic signal processing situations, especially in those system requires accurate signal conditioning like ultra-fast ADC system.
