Low Power Low Noise CMOS Chopper Amplifier

AbstractChopping is a proficient way to reduce the low frequency offset and 1/f noise in amplifiers. In this paper, a low power low noise CMOS chopper amplifier is presented. It is composed of a two stage amplifier. The first stage’s high output impedance and the equivalent Miller capacitance of the second stage constitute together a low pass filter, which reduces the power consumption. The cir...

Frequency & 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...

Nonlinear phenomena study in serial multicell chopper

In this paper, chaotic behavior study of a five-cells chopper when it is associated to a nonlinear load is reported. The model of such system is described by a piece-wise smooth six dimensional non-autonomous system. Then, some basic dynamical properties, such as Poincaré mapping, first return map and continuous spectrum are investigated to highlight the main characteristic of this particular c...
