Push pull circuit using complementary transistor and CMOS driving stage

Published:2011/4/19 22:38:00 Author:May | Keyword: Push pull, complementary transistor, CMOS driving stage

Push pull circuit using complementary transistor and CMOS driving stage
It is using CMOS inverter 4049 as driving stage of inverter stage of TDA4700 's output signal and transistor T1, T2. Three inverters are parallel. Two output ends among them are separately adding to the base of two transistors in push pull circuit. Resistor R2 is used for controlling the circuit. When it can not guarantee enough voltage for SIPMOS tube's gate pole to offer a fixed potential, it can prevent the error breaking over of this tube. Capacitor C3 is used for shorting time constant R2CBE. Here, CBE is capacitor between base-emitter of transistor T. (View)

Adjustable constant temperature controller circuit diagram

Published:2011/4/19 4:36:00 Author:Nicole | Keyword: constant temperature controller

The adjustable constant temperature controller circuit is asbelow. REF01E provides TMP17 with 10V high steady power supply, it can obtain a voltage singal from resistor R1, the voltage is in direct proportion t0 the measured temperature t. AD790 is a voltage comparator. If t represents the measured temperature and to represents the set value, when t>t0, the output of constant temperature controller is low level, when t<t0, it is high level. The value of to can be adjusted by potentiometer PR. C1 is denoising capacitance, C2 is accelerate capacitance. The output terminal of temperature control circuit controls the electric heating device by means of all kinds of actuators, then to achieve temperature control. (View)
