A new integrable fully-balanced current-tunable in phase-lead all-pass filter is presented. The architecture of the circuit is relatively simple and symmetry with differential signals consisting of merely 6 NPN Bipolar transistors. Without external resistors and matching condition the proposed circuit is very appropriate to further develop into an integrated circuit. Simulation results shown that: frequency is a function of bias current- the increasing currents effect the higher frequency frequency is a function of capacitance low-power-consumption and the maximum useful frequency of 250 MHz
