Super Steady Zener diode voltage regulator circuit
This circuit is used for controls the voltage battery is steady, which the Zener diode voltage regulator circuit apply very low current about 1mA only, cause there is ripple voltage about 1 mV at voltage changing between 10 to 30 volts. As circuit the output is fixed to 8V. In …
Complementary common-emitter circuit
This complementary common-emitter circuit has special feature that can be applied in 2 model. – Low distortion buffer – The low power output circuit How it works In Figure 1 quiescent current flow through T1 and T2 as voltage (U) and R1, R2 sequence. Look at the circuit will see …
The CMOS current controlled oscillator circuit (CCO)
We can use a CMOS nand gate or inverter gate and two transistors into the current controlled oscillator circuit (CCO). In Figure 1 use two inverters are connected together as a astable multivibrator circuit. Figure 1 the normal astable multivibrator CCO circuit. If the output of N1 is “0”, and …
Non-inverting integrator circuit using op-amp
This is non-inverting integrator circuit that is improved that below. The obstacles of old integrator as Figure 1, is Connection of RC is at a virtual ground, cause C into the capacitive load across output of op-amp. It makes an impact on the Slew rate of the circuit. May solve …
Voltage to Frequency Converter Circuit
This voltage to frequency converter circuit use the CA3130 OP-Amp ICs, that linearity Of changing is very well up to 0.5% and Temperature coefficient of less than 0.01% per degree Celsius. In Figure 1, IC1 act as the frequency generator is controlled by voltage. Suppose, first the output voltage of …
Simple resistive load
This is simple resistive load,Sometimes we need to use a resistors that without capacitance or inductance. We always use the carbon resistors. But some working to need the resistor that has also many high power. Which we cannot use the carbon resistor because it has maximum power about 2 watts …
Tremolo Effect Circuit using uA741
The tremolo effect circuit widely used, making noise in the electronic music scene. The height of the modulation signal by low frequency between 1 Hz to 10 Hz. This result will sound good, When frequency be modulated in sine. Figure 1 Tremolo Effect Circuit using uA741 The circuit as Figure …
