A current-mode general nth-order filter configuration using current mirrors is proposed in the paper. The filter uses n basic current mirrors and n unloss integrators, and can realize low pass, high pass, band pass, band reject and all pass filtering responses by changing input signal forms. As a design example, a fourth-order filter related CMOS circuit is(More)
In this paper, the characteristics of the basic current mirror and the continuous-time current-mode current mirror integrator are analyzed. Using the two unlossy loop integrators and the basic current mirrors, the biquad circuit block is implemented. The signal flow graph (SFG) and the improved leap-frog (ILF) structure are simple to implement the six-order(More)
The purpose of this study was to examine the effects of 18β-glycyrrhetinic acid (GA), a novel naturally derived agent, in suppressing prolactin (PRL) hyperactivity and reducing antipsychotic-induced hyperprolactinemia (hyperPRL) and the underlying mechanisms in in vitro and in vivo models. GA treatment for 24 h inhibited PRL synthesis and secretion in MMQ(More)
