Tuning System for CMOS HF Analog Filters

A profound study of a new digital AT (auto-tuning) technique for analog filters over very HF (high frequency) applications is reported in this paper. A 3% precision matching a 3rd-order LPF (low pass filter) characteristic frequency is shown using a 0.35 mum CMOS technology. The system consumes less...

Description
Summary:A profound study of a new digital AT (auto-tuning) technique for analog filters over very HF (high frequency) applications is reported in this paper. A 3% precision matching a 3rd-order LPF (low pass filter) characteristic frequency is shown using a 0.35 mum CMOS technology. The system consumes less area, power and tuning time than other proposed schemes. Post-layout simulation results show the building viability in a 10 MHz LPF
