Lateral pnp current gain calculation

When a standard bipolar process is used in which there are vertical NPN transistors and lateral pnp transistors it is sometimes difficult to assess the lateral PNP parameters. This post addresses a way to estimate the current gain (BETA)of a lateral PNP from its geometry. The paper which describes this technique is located in the Signal Processing Group Inc., website at Interested readers are invited to peruse this article at their convenience.
