In this paper. a new bipolar junction transistor (BJT) based configuration for providing first-order resistorless current-mode (CM) all-pass. low-pass and high-pass filter responses from the same configuration is suggested. The proposed circuit called as a first-order universal filter possesses some important advantages such as consisting of a few BJTs and a grounded capacitor. https://parisnaturalfoodes.shop/product-category/super-adult-probiotic/
