Title: Differentiation circuit
Inventor: SEKINE MASATO
IPC: G11B5/09
Filed: 1989-06-09
Abstract: PURPOSE:To simplify a circuit by attenuating a high-pass noise component by reducing impedance at a high-pass area between the collectors of first and second transistors TR with the capacitor of a parallel circuit, and eliminating occurrence of a DC offset voltage by setting the collectors of two transistors at the same potential in DC fashion with the inductor of the parallel circuit. CONSTITUTION:Differential output Eo as shown in continuous line DL is generated between first and second terminals 3a and 3b at a prescribed frequency fo or less by differentiating an input signal V1 with the inductor L. Also, the impedance between the collectors of the first and second transistors Q1 and Q2 is reduced at the high-pass area with the capacitor C of the parallel circuit 6, and the noise component at the high-pass area can be sufficiently attenuated by reducing the high-pass gain of a differential amplifier 5 as shown in broken line Dh3. Thus, by setting the impedance of the inductor L of the circuit 6 at nearly zero in DC fashion, and setting the potential between the collectors of the transistors Q1 and Q2 at the same potential in DC fashion, a DC offset voltage can be prevented occurring between the terminals 3a and 3b.
