    and jitter requirements of the end application. In high performance applications, low jitter and low phase noise are critical given that they have a direct impact on the bit-error rate in high speed serial data transmission applications and the signal-to-noise ratio of analog to digital data converters
  • Temperature Measurement Circuits for Embedded Applications
    will be compared with a frequency output RTD oscillator circuit, along with design examples using serial and analog output silicon Integrated Circuit (IC) sensors. In addition, a Programmable Gain Amplifier (PGA) circuit will be shown that can increase the effectiveness of the Analog-to-Digital Converter (ADC) bit
  • 16HV785: Programmable Lead Acid Battery Charger
    The 16HV785 provides an unprecedented level of configurability for charging lead battery packs. Its precise, 10-bit Analog-to-Digital converter and high-frequency Pulse-Width Modulator enable the 16HV785 to provide optimum control of charging algorithms for lead battery chemistries. Special
  • Sensor Sense: Capacitive Touch Sensors
    Many people mistake the growth in capacitive touch sensors as the adoption of new technology. But the fact is advances in mixed-signal programmable devices, those that combine analog and digital into a single package, have brought back this quite old technology and given it new life. The commercial
  • Agilent: Five Hints for Debugging Microcontroller-Based Designs
    Hint 1: Verifying quadrature encoder signals in a motion control system Using a mixed analog and digital signal oscilloscope to simultaneously monitor the signal levels of a quadrature encoder, an LS7083 converter chip, and a motor's positive lead. Hint 2: Implementing a simple voltage follower
