Title: Integrated circuit design technique tolerable for process
Inventor: SHOJI MASAKAZU
IPC: H01L27/04
Filed: 2000-03-08
Abstract: PROBLEM TO BE SOLVED: To make a circuit operation parameter substantially immune to a process change, by constituting a circuit so that an environmental parameter affecting the operation parameter of an integrated circuit is a function of one or more process parameters. SOLUTION: A voltage regulator circuit 30 comprises transistors M7 and M8 and a load resistor R, and so designed as to generate a reference voltage Vrfe which is so selected that an oscillation cycle of a ring oscillator circuit 20 is substantially independent of a process change. A voltage follower/scaler 32 is connected between a reference voltage output of the voltage regulator circuit 30 and an effective Vdd voltage input of the ring oscillator circuit 20. So, the voltage regulator circuit 30 generates a voltage which, upon application to a ring oscillator, invalidates or minimizes the effect on the oscillation cycle which is related to a process change in another way. Thus, the operation parameter of a circuit can be substantially immune to a process change.
