On The Realization of Active MURC Filter wth a Single Pole Amplifier
This paper presents the realization method of active MURC (multilayer uniformly distributed RC line) low pass filter with a single pole amplifier. The proposed circuit configuration consists of 2 MURC and one pole approximation of amplifier. The proposed circuit has a steeper rate of magnitude response at cut off and low sensitivities in the pass band. Experimental results of MATLAB simulations are carried
Active LPF using uniformly distributed RC line
The synthesis method of active low pass filters using uniformly distributed RC line has been published. This paper describes the Low Pass Filter (LPF) using double capacitive layers uniformly distributed RC line (DURC). This LPF circuit configuration with notch characteristics consists of DURC and a positive gain amplifier. The LPF using DURC can be used for anti-aliasing/smoothing filters for signal processors.
Transistor-only frequency-selective circuits
The distributed characteristics of an MOS transistor operated in the strong inversion nonsaturation region are summarized, including small-signal characteristics and large-signal nonlinearities. A procedure for converting an active distributed RC circuit to a transistor-only circuit is introduced. Preliminary experimental results for a 100-MHz lowpass filter test chip are presented. The experimental results obtained are encouraging in showing the potential of implementing noncritical transistor-only filters and oscillators as part of VLSI chips fabricated using 'digital' technologies in which transistors are the only available circuit elements.<<ETX>>
