Figure 1 555 VCO discharges timing cap C1 completely to the negative rail via a Reset pulse. The nay-sayers’ case hinged on a perceived inability of the 555 architecture to completely discharge the ...

This article introduces a novel high-sensitivity readout circuit that leverages the resonant amplification effect of the LC network in an oscillator to generate high-voltage excitation signals. By ...

Part 1 shows how to make an oscillator with a pitch that is proportional to a control voltage. Part 2 shows how to modify the circuit for use with higher supply voltages, implement it using discrete ...
