PISA – what’s wrong with Sweden
The Swedish education system used to be a good example, but looking at the new PISA results, Sweden is among the countries with the strongest deterioration in school education in reading, mathematics and science. The only thing Sweden has achieved is to narrow the gap between top and low performers – obviously by lowering the… Continue reading PISA – what’s wrong with Sweden
MOSFETs – what the datasheet doesn’t tell you
I am planning to construct a logarithmic current meter and were yesterday doing some simulations with LTspice. Using a logarithmic converter you can span a wide range of currents with a single readout without the necessity to switch ranges. Of course this has disadvantages as well, but if you know what you are doing it… Continue reading MOSFETs – what the datasheet doesn’t tell you
