An Improved Version of the MAE555 Highly Stable Controller with Greater Temperature Insensitivity
Original language description
An improved version of the 555 highly stable controller has been prepared on the basis of modified MAE555 chip, packaged as A90. The goal of the design was to improve primarily the temperature stability of the timer, which was still questionable in the classical versions of the circuit. The attention was turned especially to the four Darlington pairs of the circuit (npn ones Q1+Q2 and Q3+Q4, and pnp ones Q10+Q11 and Q12+Q13 in the standard equivalent schematic). For improving the circuit, both standardSPICE and our CIA (Circuit Interactive Analyzer) programs have been used. Originally, the SPICE standard data file was obtained and converted automatically to the CIA input language using our software "ConvWin for CIA." This original software prepared for similar purposes has been created by the Delphi development system, and is able to convert practically arbitrary SPICE input file to the CIA one. The advantage of the CIA program with respect to the SPICE one consists in the ability to
