چکیده انگلیسی
The simple square-law MOSFET model fails to describe the behavior of short channel and moderate/weak inversion devices. The gm/ID methodology is a promising technique that addresses the square-law shortcomings and bridges the gap between hand analysis and simulation. This paper describes a systematic procedure for the design of a single-stage operational-transconductance amplifier (OTA) using the gm/ID methodology. Both small signal and large signal specifications are used to constrain the design process, which is graphically illustrated using trade-off charts. The presented design procedure is automated using MATLAB, and an iterative procedure is used to take the OTA self-loading into consideration. Moreover, an automated optimization procedure is presented to maximize the speed of a unity-gain buffer under current consumption, DC gain, and input capacitance constraints. The designed circuits are verified using Cadence Spectre and the 180â¯nm Predictive Technology Model (PTM), where the simulation results are in close agreement with hand analysis and automation results.
