Modulation and System Techniques in PWM and SDM Switching Amplifiers*
Continuousand discrete-time switching audio power amplifiers are studied both with and without feedback. Pulse-width modulation (PWM) and sigma–delta modulation (SDM) amplifier configurations are simulated and their interrelationship is described using linear phase modulation (LPM) and linear frequency modulation (LFM). Distortion generation encountered when applying negative feedback to PWM is...
متن کاملGm-C Chopper Amplifiers for Implantable Medical Devices
In this paper two different Gm-C chopper amplifiers, aimed for signal amplification in implantable devices are presented. The first one is a pre-amplifier for ENG signals that was fabricated in a 1.5 μm technology. Measurements of this amplifier showed input noise of 1.2 nVHz and 2.5 μV offset with a power consumption of 28 mW. The second is a complete amplifier for EEG signals designed in a 0....
متن کاملReducing File System Tail Latencies with Chopper
We present Chopper, a tool that efficiently explores the vast input space of file system policies to find behaviors that lead to costly performance problems. We focus specifically on block allocation, as unexpected poor layouts can lead to high tail latencies. Our approach utilizes sophisticated statistical methodologies, based on Latin Hypercube Sampling (LHS) and sensitivity analysis, to expl...

15 صفحه اولFrequency & duty cycle control considerations for soft-switching buck chopper
This paper presents considerations on the switching frequency and duty cycle & operating equations of softswitching BUCK chopper. These considerations are discussed and applied to selected soft-switching families such as ZVS-QRC, ZCS-QRC, ZVS-QSW-CV, ZCS-QSWCC, ZVT-PWM and ZCT-PWM [1]. The limitations on switching frequency and duty cycle are derived in terms of: chopper input voltage (Vg), cho...
