The Voltage Pile Transistor Quantizer

Summary - This paper describes a simple and novel form of analog-to-digital converter which is completely transistorized and does not require any stepping or counting devices or any null-sensing element. This converter can be used either to generate digital values or as a limit-value selector. Transistorized circuitry of the limit value selector has resulted in a simple, accurate, and practical approach to automatic testing and sorting machines. A specific application in a machine for testing and sorting transistors is described.
