Timer circuit using OTRA and its application as astable and Monostable multivibrator

This paper presents a new AnalogTimer circuit which is used to design A stable and Monostable multivibrators. The circuit employs comparators designed using OTRA and and flip flops implemented using N and gates. As table multivibrator designed using this Timer circuit generates a periodic waveform of variable time period and duty cycle. Monostable multivibrator uses a current trigger pulse to produce the output. The proposed circuits are insensitive to parasitic capacitances and resistances due to internally grounded input terminals of OTRA and can operate at very low power supply voltage [1]. The performance of the proposed Timer circuits is verified through PSPICE simulation using 0.5 μm CMOS process parameters provided by MOSIS (AGILENT).
