 ==IC Design==
 As you go smaller you get less voltage but go faster and have higher frequency. Therefore, instead of measuring voltage or current you might measure frequency changes, because high frequency is more accessible than access to voltage or current. Per amp hour 579.

+Two fundamental DACs
-* Resistor String DACs
+* Resistor String DACs (discrete)
 * R-2R Ladder DACs
 The Resistor String type will require (large) amounts of resistors and analog switches. These are practical on a chip (e.g. AD5689, DAC8564). This is 2 to the power of N resistors.

-The R-2R Ladder type uses quite a bit less, and is practical for circuit board assembly from discrete components. Reference: Practical Electronics June 2025, Page 72. This is 2 x N resistors (N being the bits).

 Also consider the technique in the magazine of a complementary (inverted, I think) PWM signal along with a normal signal to speed up the settling time. (Page 73).
