Balancing Power and Precision in Stochastic Computing
![For CMOS chains, reliability against bit-flip errors increases exponentially with bias voltage but sub-exponentially with chain length, creating a performance envelope where a fixed dissipation budget is best utilized by minimizing chain length and maximizing bias voltage - a relationship governed by the circuit’s characteristic timescale [latex]\tau\_{0}=\frac{e}{I\_{0}}e^{V\_{\rm th}/(nV\_{T})}[/latex].](https://arxiv.org/html/2603.04658v1/2603.04658v1/x3.png)
