Low-voltage Switched-capacitor Resonators
The recent explosion of interest in wireless personal communication systems motivates the development of fully integrated radio receivers. The parallel reduction of the feature sizes in CMOS technology, and hence higher levels of integration. enable the combined integration of a bandpass or baseband analog-to-digital converter with the traditional front-end receiver building blocks. While ths t...
متن کاملLow-voltage switched-capacitor circuits
One of the key limitations of state-of-the-art fine linewidth CMOS technologies is the restricted power-supply voltage, limited by the low junction-breakdown voltage of the process and by the thin gate oxide, prone to voltage stress and breakdown. Also, in some applications, the available external power source may limit the supply voltage; for example, this source may be a 1.2 V battery, with a...
متن کاملLow-Voltage High-Speed Switched-Capacitor Circuits Without Voltage Bootstrapper
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...
متن کاملStable differential voltage to frequency converter with low supply voltage and frequency offset control
In this paper, the circuit for a new bipolar differential voltage-to-frequency converter is presented. The circuit operation and the calculation of the operating frequency are described. The circuit design is also realized using Zetex transistor array integrated circuits and a 3.3-V power supply. This circuit incorporates an adjustable operating frequency via an external capacitor. The operatin...
متن کاملAlternating Voltage Tests on Distribution Transformers Using Static Frequency Converters
This paper presents experience in performing alternating voltage measurements on distribution transformers using a static frequency converter without particular control scheme. Regarding induced voltage tests, no-load and load measurements, the quality, i.e. the degree of distortion and the symmetrical shape, of the generated test voltage, deviations in measured power and the relation between d...
