A first stage operational amplifier (without external capacitors) provides part of the gain required. This is followed by a second stage switched capacitor high pass filter (without external capacitors) that provides the remaining gain required while filtering out the DC offset of the first stage operational amplifier. In order to cover the range of frequencies expected without aliasing problems, two switched capacitor high pass filters in parallel are used, each designed with a different cut-off frequency."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Shock detector with DC offset suppression using internal components","description":"A shock detector, such as for disk drives, which eliminates discrete external capacitors used in prior art devices.
