Design of Pass Filter for Multi-amplifying
Wang Li · Microelectronics & Computer · 2006
This paper introduces a design of low pass filter for programmable amplifying and cutoff frequency by single-chip computer. It uses a Switched Capacitor Filter and a IC Instrumentation Amplifier for basic functional components. We discuss specially a new method for multi-cutoff frequency and multi-amplifying based on switched capacitor filter and nonvolatile digitally controlled potentiometer.
