Only with a single chip active component (4069 IC), this circuit will convert sine to square waves without a power-source. To test some audio instruments, we can use this circuit. Device purpose: This circuit intended to pick up the a sine wave from an existing generator and then converts that wave into good square waves. This circuit doesn’t need power-source, […]

In some industries, to control the some equipments they are use computer-controlled 4-20mA current loop. This current loop is used transmit a signal over a long distance wires. With current loop, the signal will be resistant from noise interference. To operate this computer-controlled 4 – 20mA we need a single power supply with a range of 3.3 to 30V. On […]

A frequency-selective frequency multiplier can be construct with a PLL system by inserting frequency divider inside the feedback between the phase detector input and the VCO output. Figure below shows the schematic diagram of low-frequency synthesizer with a programmable three decades divider circuit. The frequency-divider modulus N have value between 3 to 999 with single steps increment. In locked condition, […]

To extend the measurement range of an available ADC(analog to digital conveter) we can use this autoranging. If it implemented on multiplexed input, this circuit will give best result. To adjust an ADC’s full-scale range we use a system autoranging that use LTC1257 because it is appropriate for system autoranging. During the conversion process, U2 and U3 receive the full […]
