Crystal load capacitance – In the book, Experimental Methods in RF Design”, the authors state that “Our crystal had marked frequency of 7045 KHz. This was the specified frequency for operation with a 32-pF load capacitance.” If I had a 20MHz crystal, how will I know the exact value of its load capacitance? Read more […]

Miniature OCXO measures 9.7 x 7.5. mm
IQD’s latest Oven Controlled Crystal Oscillator (OCXO), the IQOV-71 series, is housed in 4-pad plastic package with a fibre glass base measuring only 9.7 x 7.5mm. Despite the ultra-small size, the new model offers very low frequency stabilities down to ±10ppb over an operating temperature range of -20 to 70 degrees C or ±20ppb over […]
Zero-drift precision op amp simplifies board design
Analog Devices has introduced the first in a new series of high-voltage, low-noise, zero-drift, precision operational amplifiers. The dual-channel ADA4522-2 op amp reduces reduce system noise, cost, board space, and development time by providing on-chip electro-magnetic interference (EMI) filtering and eliminating the need for calibration circuitry. The ADA4522-2 op amp operates within a supply voltage range […]

Calculating and comparing amplifier noise
I was recently presented with the problem of comparing the noise of two alternative designs that were presented to me. Normally that wouldn’t take much sorting out – a few minutes with a SPICE simulator and you would have the answer. That depends on having reliable SPICE models. The first thing I do when embarking […]
