This paper describes the conception of the current follower transconductance amplifier (CFTA) with electronically and linearly current tunable. The newly modified element is realized based on the use of transconductance cells (G(m)s) as core circuits. The advantage of this element is that the current transfer ratios (i(z)/i(p) and i(x)/i(z)) can be tuned electronically and linearly by adjusting...

Infinite Impulse Response (IIR) test-chip that has been designed using a novel chargerecovery logic family, called Enhanced Boost Logic (EBL), to achieve high-speed and low-power operation. EBL achieves increased gate overdrive, resulting in low latency overhead over static CMOS design. The test-chip has been fabricated in a 0.13 m CMOS process with a fullyintegrated 3 nH inductor. The biquad f...

Low-voltage high-speed switched-capacitor (SC) circuit design without using voltage bootstrapper is presented. The basic building block used for low-voltage SC circuit design is the auto-zeroed integrator (AZI), which can work at both low voltage and high sampling frequency. With this method, two low-voltage SC systems were successfully designed and implemented in 1.2m CMOS technology. The firs...

This paper presents a low-cost analog test system with diagnosis capabilities. The tester is able to detect faults in any linear circuit by learning a reference circuit behavior in a first step, and comparing this behavior against the output of the circuit under test in a second step. For a faulty circuit, a third step takes place to locate the fault. The diagnosis method consists on injecting ...

This paper presents a new multiple-input single ?output voltage-mode universal biquad filter based on multiple?input operational transconductance amplifiers (MI-OTA). work demonstrates that the OTA?based can provide more filtering responses and other benefits, compared to conventional one. The provides electronic orthogonal control of natural frequency quality factor. Furthermore, two-phase qua...

To enhance the reliability of analog circuits in electrical systems, this letter proposes a novel incipient fault diagnosis method by integrating wavelet transform(WT) and improved convolutional neural network. Different from traditional methods, where feature extraction classification are separately designed performed, aims to automatically learn features classify type faults simultaneously. A...
