| description | This paper describes a highly sensitive CMOS chopper amplifier for a monolithic magnetic hall sensor. It is realized by using chopper stabilization technique to overcome the low frequency noise and drift problems. In order to eliminate the residual offset due to input switching transient spikes, we choose a double track-and-hold (T/H)-based demodulation. This chopper amplifier can effectively eliminate the amplifier input offset, low-frequency input noise components and residual offsets due to input switching spikes, without requiring any low-pass filtering. |
