S / R ( set / reset ) pulse generator circuit ( integrated magnetic field sensor HMC1001/1002 )

Published:2012/10/7 21:39:00 Author:Ecco | Keyword: S / R , set , reset, pulse generator, integrated, magnetic field sensor

S / R pulse is set / reset pulse, of which amplitude depends on the measurement sensitivity of the MR sensor. For example, Tesla meter is composed of HMC1001/1002, when the minimum measurable flux density is 50nT, the amplitude of pulse current is required not less than 3A; when the minimum measurable flux density is 10 nT, the pulse current amplitude is not less than 4A. The higher measurement sensitivity is, the higher pulse current amplitude is. The circuit uses a microprocessor circuit to generate the S / R pulse, and the circuit is shown as the figure. This circuit uses +16 ~ +20 V power supply, and the pulse current can be more than 4A.   (View)

Pulse generator circuit using two complementary transistors

Published:2011/10/31 1:58:00 Author:May | Keyword: Pulse generator , two complementary transistors

It usestwo complementary transistorsto produce pointed pulse with theamplitude in 8V, rise time in 50nS+. This circuit pulse intermission is 1.4ms at the situation of charging capacitance is 10nF and 1M potentiometershort-circuited, and the weakening or decreasing capacitance value can make the pulse intermission increase or decrease. If 820Ω resistor isconnected at the emitter of NPN transistor instead of series with capacitor, it will get sharp pulse output.   (View)

The pulse generator circuit with sharp pulse and sawtooth pulse

Published:2011/11/27 21:05:00 Author:Ecco | Keyword: pulse generator , sharp pulse , sawtooth pulse

The upper limit of the two pulses' frequency generated by the gate circuit is 5MHZ, the lower limit depends on the size of the capacitor . Sharp pulse width is about 50ns, which is output directly from TTL and non gate; sawtooth pulse is generated by impedance converter, which is a Schmitt trigger with high input impedance, so that it has a good sawtooth linearity . Gate device substitution : FLH731-49713S, FLH491-49702.   (View)

Schematic and applied circuit diagram of pulse circuit composed of photoelectric coupler

Published:2011/9/9 7:54:00 Author:Vicky | Keyword: Schematic and applied circuit diagram, pulse circuit composed of photoelectric coupler

picture1 picture2 When Ec is just on in picture 1(a), Up increases when C is charging. When UF≈1, luminous diode and then the triode become saturate, and output Uo≈Ec. When triode becomes saturate, C discharges (through two route: C→F→E1→Er and C→RF→+Ec→R ). Uo becomes lower. The diode stops when c discharges to a certain degree. The triode stops subsequently after moving all the memory electric charge, and uo becomes zero. Power Ec charges C again after triode stops, and the above process repeats again. Thus the peak output wave is obtained, and the cycle is (when RF》Re ): T=C（RF+Re）In2   (View)

Complementary tube pulse circuit principle and applied circuit diagram

Published:2011/9/9 7:51:00 Author:Vicky | Keyword: complementary tube pulse circuit

(picture1) Complementary tube bistable state circuit is shown in picture1(a). When the power is on, if no triggering signal works, the two tubes stop working and the state is in a stable state because the collector current is extramely small, and the end voltage of RC1, and Rc2 (bias current provided to the two tubes) is also very small. When the trigger pulse is working, suppose that BG1 becomes amplified from static, and leads to the process of avalanche-type positive feedback. Soon the two tubes become saturate, and are in another stable state. Capacitance C1 is speed-up capacitor. From picture1（b）， we can see that uc1 goes down to zero sharply from Ec, while Uc2 zooms up to Ec from zero.   (View)
