Purpose - The paper aims to present a simple rail-to-rail CMOS voltage follower.
Design/methodology/approach - The circuit is developed based on a complementary source follower with a common-source output stage. The circuit is designed using a 0.13 mu m CMOS technology, and operates under the supply voltage of 1.5 V. HSPICE is used to verify the circuit performance.
Findings - The simulations show output voltage swing of /- 0.6 V (300 Omega load) with the total harmonic distortion of 0.55 per cent at the operating frequency of 3 MHz. The bandwidth and power dissipation are 657 MHz and 405 mu W, respectively.
Originality/value - A simple rail-to-rail CMOS voltage follower is presented.
