A universal continuous-time CMOS log-domain second-order building block is presented. The proposed circuit utilizes MOS transistors operating in weak inversion, therefore, it can operate with low supply voltage. The circuit has very low power dissipation. The theoretical analysis have been carried out and verified by HSPICE simulations
