Resistor-capacitor-transistor type integrated circuit, method for the manufacture of such a circuit and application to an oscillator

摘要

A resistor-capacitor-transistor type of integrated circuit comprises mainly a non-self-aligned N diffusion bar 1 covered with a polysilicon plate, and a drain type N diffusion, self-aligned by the polysilicon plate. The resulting structure is a distributed resistor- capacitor- transistor quadripole whose main characteristics are that it is very compact and that the time taken by the capacitor to get discharged through the transistor is independent of the dimensions of the structure.
