Title: Full-wave rectifying circuit
Inventor: KATAKURA MASAYUKI
IPC: H02M7/12
Filed: 1981-11-30
Abstract: PURPOSE:To perform full-wave rectification with high accuracy and to decrease the number of connecting terminals down to just one when a monolithic integrated circuit is formed, by providing an operational amplifier, impedance circuit, feedback circuit and current inverting circuit. CONSTITUTION:The input signal supplied from an input terminal 1 is applied to a noninverse input terminal of an operational amplifier 11. The amplifier 11 drives an npn transistor TR12 and pnp TR13. The emitters of these TRs 12 and 13 are connected to a common output point 14. An end of an impedance circuit 15 having frequency characteristics is grounded, and the other end of the circuit 15 is connected to the point 14. The point 14 is connected to an inverse terminal of the amplifier 11 to form a negative feedback circuit. The collector current of the TR12 is added to the collector current of the TR13 via a current inverting circuit 16 and then taken out to an output terminal 19 in the form of an output current. In such a way, the full-wave rectification is ensured with high accuracy. Furthermore, the number of connecting terminals can be decreased down to just one when a monolithic integrated circuit is formed.
