Your original list of cap values covered a wide range (150pF to 1uF, 4 decades), which is a bit of a stretch. Similarly, resistors from a few hundred ohms to several megohms is a bit of a stretch.<br>
<br>
If you used a few standard cap values (Say 1n, 3n3, 10n, 33n and 100n) you’d be able to find all the caps from the same range, and you’d be able to keep the resistor values within a tighter range and not push the performance of other stuff in the circuit (like running op-amps with very low or very high input impedances, for example).<br></blockquote></div></div></div><div dir="auto"><br></div><div dir="auto">Almost exactly like Jürgen Haible did in the phase-displacement RC links of his frequency shifter some 10 years ago IIRC. :-)</div><div dir="auto"><br></div><div dir="auto">/mr</div><div dir="auto"><br></div><div dir="auto"><br></div><div dir="auto"><div class="gmail_extra"><div class="gmail_quote"><blockquote class="quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><br></blockquote></div></div></div></div>
