  2. Oscillators Texas Instruments CD74HC02 CD74HC30 CD74HC390
    This project originated from the need to produce a linear crystal-controlled ramp signal for an HP 8620C RF sweep oscillator. It is inspired by a previously published ramp generator design [ 1 ]. That design though suffered from two issues: it used ...
