GENERATION OF OSCILLATORS BASED ON GROUNDED CAPACITOR CURRENT CONVEYORS WITH MINIMUM PASSIVE COMPONENTS

摘要

In this paper, eight new Frequency Dependent Negative Resistance (FDNR) circuits using two current conveyors or inverting current conveyors or a combination of the two types are introduced. The proposed circuits are canonic and they use two grounded capacitors and one floating resistor. The generation of grounded capacitor minimum passive component oscillators from the FDNR circuits is also considered. It is found that two of the recently reported attractive oscillators are among the family of the generated oscillator circuits. Additional six new oscillator circuits based on the FDNR circuits are introduced in this paper. Spice simulation results using technology: SCN 05 feature size 0.5 μm, MOSIS Vendor: AGILENT to demonstrate the practicality of the proposed oscillators are included.
