Converter Circuits

100s of converter circuits for every hobbyist, technician, student, and design professional. An nice reference tool which includes lots of converters. look at these circuit ideas, some of them may need some modification if they are to work as advertised. Ideas along with pretty good descriptions for each circuit.

Frequency/Voltage Converter

Teledyne Semiconductor"s Type TSC9402 is a versatile IC. Not only can it convert voltage into frequency, but al..

Simple 2M 6M Transverter Circuit

Using the bilateral properties of a balanced mixer this transvertcr will produce 6-m output with 2-m inputs. Y1 is a 90-MHz crystal. Note that the input on 2 m is 143 to 144 MHz for 53 to 54-MHz output. This avoids possibility of extraneous 2-m reception during receive periods...

Voltage-to-requency-converter

Circuit has a 1 Hz-to-30 MHz output, 150-dB dynamic range, for a 0 to 5 V input. It maintains 0.08% linearity over its entire 71/3 decade range with a full-scale drift of about 20 ppm/Â°C. To get the additional bandwidth, the fast )FET buffer drives the Schottky TTL Schmitt trigger. The Schottky diode prevents the Schmitt trigger from ever seeing negative voltage at its input. The Schmitt"s input voltage hysteresis provides the limits which the oscillator runs.....

Period-To-Voltage Converter

The input signal drives ICD. Because ICD"s positive input (V+) is slightly offset to + 0.1 V, its steady state ..

Voltage-To-Frequency Converter I

Using a Burr-Brown VFC 32 IC, this voltage-to-frequency converter uses few components. The circuit values ..

Voltage-to-frequency-converter

The input voltage, V1, causes C1 to charge and produce a ramp voltage at the output of the 741 op amp. Diodes D1 and D2 are four-layer devices. When the voltage across C1 reaches the breakover voltage of either diode, the diode conducts to discharge C1 rapidly and the op amp output goes abruptly to zero. This rapid discharge action applies a narrow pulse to G1 and G2. Positive discharge pulses produced by a positive V1 are coupled to the output only through G1, while.....

Power-Saving Intermittent Converter

This circuit switches its dc/dc converter, IC1, off whenever the large filter capacitor, C6, has suffic..

Frequency-to-voltage converter

In these applications, a pulse input at % is differentiated by a C-R network and the negative-going edge at pin 6 causes the input comparator to trigger the timer circuit. Just as with a V-to-F converter, the average current flowing out of pin 1 is IaverAGE = i (1.1 RjC^ f. In this simple circuit, this current is filtered in the network RL = 100 k ohm and 1 ÂµF. ..

Crystal Controlled Frequency Converter Circuit

The second gate (G2) of a MOSFET can be used to incorporate a crystal oscillator into the same stage as a frequency mixer. Although old hat with tubes, this scheme is seldom seen in dual-gate MOSFET circuitry. L3, 03, and XI form the crystal oscillator, and T2 is an IF output transformer. T1 and 01 are tuned to the converter input frequency. ..

800 To 1000Mhz Scanner Converter Circuit

This converter enables reception of 800 to 1000 MHz on any scanner covering the 400 to 500-MHz range. The converter can be set up to cover either 800 to 900 MHz or by readjustment 900 to 1000 MHz. Sensitivity is very high because of the GASFET front end. ..

Voltage-to-frequency-converter

This circuit can accept positive or negative or differential control voltages. The output frequency is zero when the control voltage is zero. The 741 op amp forms a current source controlled by the voltage Ec to charge the timing capacitor C1linearly. NE555 is connected in the astable mode. so that the capacitor charges and discharges between 113 Vee and 213 VeeÂ· ..

A simple circuit using a single transistor converts 220 MHz to 144 MHz or vice versa, because the mixer is bila..

DC-10Khz frequency-voltage converter

The converter generates an output voltage which is linearly proportional to the input frequency waveform. Each zero crossing at the comparator"s input causes a precise amount of change to be dispensed into the op amp"s summing junction. This charge in turn flows through the feedback resistor generating voltage pulses at the output of the op amp..
