We investigate the dielectric dispersion of water, specially in the low-frequency range, by using the impedance spectroscopy technique. The frequency dependencies of the real R and imaginary χ parts ...

Abstract: We present a very-large-scale integration continuous-time sinusoidal operational transconductance amplifiers quadrature oscillator fabricated in a standard double-poly 0.8-/spl mu/m CMOS ...

We have designed and fabricated 25-μm-thick quartz resonators operating at a fundamental resonance frequency of ∼62 MHz. The results show a substantial increase in the mass sensitivity compared to ...

A 10-b 50-MHz digital-to-analog (D/A) converter for video applications that is based on a dual-ladder resistor string is presented. This approach allows the linearity requirements to be met without ...

The spectrum up for auction is divided into three groups: 1. Low Band: 850 MHz (824–834 MHz paired with 869–879 MHz) — minimum bid per lot is 7.738 billion baht, with 2 lots available (each lot is 2x5 ...
