6th Great Lakes Symposium on VLSI
A 3V-50MHz Analog CMOS Current-Mode High Frequency Filter with a Negative Resistance Load
Ames, IA
March 22-March 23
ISBN: 0-8186-7502-0
A low voltage Analog CMOS current-mode continuous time high frequency filter with a negative resistance load (NRL) is proposed. To design a current integrator, we use a modified simple current mirror with a NRL to increase the output resistance. The current integrator is designed to have the frequency behavior enhancement and operate in low voltage by employing a simple mirror structure and diode connected input transistor. The third order Butterworth low pass filter using a current integrator is Synthesized and simulated with a 1.5μ n-well process. Simulation result shows cutofj-equency of 50 MHz and power consumption of 2.4mW/pole with a 3Vpower supply.
