Novel current-mode active filter circuits using current-conveyors are presented. The proposed circuits can realize all standard second-order filter functions. The circuits enjoy high output impedances and can, therefore, be easily cascaded to produce higher order filters. Moreover, the realized filter function can be easily programmed using at most a 13-bit digital number without changing the circuit topology.

Transconductance Amplifiers

Novel CMOS current mode shapers for front-end electronics are proposed. In particular, six semi-Gaussian shaper implementations based on second generation current conveyors and operational transconductance amplifiers are designed using advanced filter design techniques. Although all shaper architectures are fully integrated, they satisfy a relatively large peaking time. The topologies are analytically compared in terms of noise performance, power consumption, total harmonic distortion (THD), and dynamic range (DR) in order to examine which is the most preferable in readout applications. Design technique selection criteria are proposed in relation to the shaper structures performance. Analysis is supported by simulations results using SPICE in a 0.6 μm process by Austria Mikro Systeme (AMS).
