Abstract :
An in-depth study of CMOS transconductor designed negative resistance circuits is presented. Important large signal and small signal characteristics including noise, stability and bandwidth are investigated. A strategy of designing large bandwidth active resistors is proposed with supporting analysis. Key stability issues that have not previously been reported are discussed. Finally, applications which include the design of a low phase noise current mode oscillator and a high bandwidth inverting amplifier are demonstrated with simulation results.
