Abstract :
Using novel backward- and forward-mapping types of SC (switched capacitor) differentiators, three types of biquad are designed and analyzed. Their functions have been verified through chip fabrication and measurement. Performance evaluation and design guidelines are given for the optimal design of high-order SC filters
