Reconfigurable pseudo floating-gate analog circuits

In this paper we explore the bi-directionality of pseudo floating gate analog circuits. The basic pseudo floating-gate current starved inverter is symmetric with respect to the supply rail, and the signal flow can be altered by flipping the supply rails. Different circuits configurations, including a differential to single-ended amplifier, single-ended to differential amplifier, follower integrator and differentiator circuits are presented. The simulated data are obtained using the SpectreS simulated provided by Cadence and valid for a 90 nm STM process.
