Linear To Exponential Converter

See page 15 of Linear Technology application note 14 for an example of this in connection with an exponential voltage to frequency converter for music applications. I wanted for once to try without an unobtanium transistor array - just press hand-matched pair of transistors together with the PTC into a piece of aluminium bar.

Exponential converter . A type of amplifier circuit used in most analog synthesizers to process control voltage inputs to voltage controlled oscillators, voltage controlled filters, and other frequency-specific processing functions. The nature of most VCO and VCF circuits is that they respond to their control voltage input in a linear fashion

Now, Delay time knob is exponential , and I can't find an equation for how its percentage values relate to the ms delays. Then linking to formula controllers doesn't work, because automating the delay time from 500 ms to 750 ms is not as simple as multiplying the initial value of the Formula controller with 1.5.

This paper presents an incremental A/D converter with a two-phase linear - exponential accumulation loop. In the linear phase, the loop works as a first-order structure. The noise coupling path is then enabled in the exponential phase thus boosting the SQNR exponentially with a few number of clock cycles. The uniform- exponential weight function ...
