A new CMOS Differential OTRA Design for the Low Voltage Power Supplies in the Sub-Micron Technologies

In this study, a new CMOS dierential OTRA topology is proposed. This topology can operate with a very low voltage power supply as 0.6V. In this design, CMOS 0.13 m STMicroelectronics technology transistor models are used for the simulations. The designed CMOS OTRA has a transresistance gain (Rm) of 7478 V/I with a 28.1 MHz bandwidth (-3 dB) and a transresistance unity-gain bandwidth of 2 GHz. To demonstrate the performance of the OTRA, designed low pass, high pass and band pass lters employing a single CMOS dierential OTRA and passive elements are tested with SPICE simulation program to verify the theoretical results.
