The settling behavior and power consumption of dynamic opamps are considered. The dynamic opamp is compared with a class A opamp for di erent clock frequencies. A single pole model in a closed loop con guration is used to estimate slewing and settling behavior. SPICE simulation results agree with theoretical predictions. It is shown that for the same power consumption dynamic opamps settle much...

Operational amplifier stability compensation methods for capacitive loading applied to TS507 Introduction Who has never experienced oscillations issues when using an operational amplifier? Op-amps are often used in a simple voltage follower configuration. However, this is not the best configuration in terms of capacitive loading and potential risk of oscillations. Capacitive loads have a big im...

A binary genetic encoding (BGE) representation for the automatic synthesis of mixed-mode circuit topologies, is introduced. First, the genetic encoding of unity-gain cells (UGCs), such as voltage (VF) and current followers (CF), and voltage (VM) and current mirrors (CM), is presented. New BGEs for the VM and CM are introduced. Second, the UGC’s chromosomes are combined to synthesize mixed-mode ...

Chua's circuit is a simple electronic network which exhibits a variety of bifurcation phenomena and attractors. The circuit consists of two capacitors, an inductor, a linear resistor, and a nonlinear resistor. This paper describes the design methodology for a robust practical op amp implementation of Chua's circuit. In addition, we present experimental results and SPICE simulations for a workin...
