The history of Tow–Thomas second-order filter is reviewed. Two alternative generation methods of the Tow–Thomas filter are discussed. The first is a generation method from the second-order passive RLC filter and the second is from the multiple feedbacks inverting low-pass filter using a single op amp. Several forms of the circuit are briefly reviewed. Passive and active compensation methods to ...

The paper describes hardware implementation of control system designs using the Quanser DC Motor Control Trainer (DCMCT). Toward this goal, students are guided to design control systems and verify their designs via simulation environments like MATLAB/Simulink. Then, they realize the control system designs by building op-amp circuits and validate the designs via the Quanser DC Motor Control Trai...

The paper presents a new approach to automate the set-up of design equations manual analog process. Its main contribution is comprehensive hierarchical performance equation library (HPEL) for op-amps. HPEL makes independent topology. Based on and functional block recognition method in [1], analytical models various op-amp topologies are automatically instantiated. currently designed basic In th...

Operasional Amplifier berfungsi untuk memperkuat tegangan searah ataupun bolak-balik. Fungsi Op-Amp dapat muncul dari dasar rangkaian umpan balik dengan jumlah besar negatifnya, kinerja tersebut ditentukan oleh komponen baliknya. Penyusunan disusun dalam sebuah yang terintegrasi atau biasa disebut Integrated Circuit (IC). Ditulisnya analisis komparator ini adalah mengetahui komparator, menganal...

A cell-impedance measurement system is presented that can measure an effective parallel resistance and capacitance of a cell to within 1% in 1ms. It is proven to be functional at ten logarithmically-spaced frequencies between 100 kHz and 100 MHz, with ten parallel structures simultaneously calculating each of these. This system is further shown to be implementable with commercial parts – namely...

This paper proposes and studies the effects of a dual-stage compensation technique for achieving greater than 100 kHz crossover frequency of a single pole system converting from 48 V to 1.2 V. By placing a separate non-inverting gain stage after the error amplifier, the necessary gain-bandwidth of the op amp can be significantly reduced allowing for high crossover frequency and good transient r...

T h e technique of mirror biasing i s introduced and applied to a very high gain two stage CMOS cascode op-amp, in order to desensitize i ts output voltage to bias variations. Various performance metrics like low frequency common mode and power supply rejection ratios, slew rate and the sensitivity of the systematic offset are substantially improved. The improved performance i s theoretically p...
