11. Add-on beat frequency oscillator (BFO) for shortwave radio
    Gavin Watkins
    Circuits Texas Instruments LP2950
    Expensive shortwave radios include beat frequency oscillators, so why not also add one to an inexpensive radio version? Broadcast shortwave (SW) radio use may be declining, but there are still lots of interesting signals to listen to between 1.6 ...

13. Dual amplifier active filters
    John Dunn
    Articles Texas Instruments LMV822
    The frequency response of a Butterworth filter is not supposed to have any peaking. SPICE claims the contrary. I came across an online datasheet for some op-amps where I found two schematics that intrigued me. Screen-shotting them together resulted ...

16. Cheap and cheerful LMC555 RC PWM pulse generator
    Stephen Woodward
    Circuits Texas Instruments LMC555
    This circuit enables you to generate remote control PWM test signals with a (very) generic (and cheap) chip. A recent Design Idea ( Ref. 1 ) illustrated the application of an interesting chip (the LTC6992 ) to remote control (RC) PWM test signal ...

17. Phantom-powered solid-state linear airflow sensor
    Stephen Woodward
    Circuits Texas Instruments TLV2197 LM7905
    Self-heated Darlingtion transistor pair linearly senses airflow using just two wires for both power in and signal out. Suppose we take a common TO-92 transistor and heat it to a constant temperature differential above ambient. The power input ...

18. Hz to 4-20mA or 0-20mA current source is compatible with grounded loads
    Stephen Woodward
    Circuits Texas Instruments LM2917
    Minimal circuit converts input frequency to a precision current source that also accommodates grounded inputs. I recently had the opportunity to share a design ( Ref. 1 ) for frequency to current loop conversion using the versatile (if somewhat ...

19. An off-line power supply
    Gavin Watkins
    Circuits Texas Instruments LM317
    One of my electronics interests is building radios, particularly those featured in older UK electronics magazines such as Practical Wireless, Everyday Electronics, Radio Constructor, and The Maplin Magazine. Most of those radios are designed to run ...

20. Build a practical 400 mA linear Li-ion charger with visible CC-CV behavior
    Richard O. Ocaya
    Circuits Texas Instruments LM324 LM431
    Single-cell lithium-ion (Li-ion) chargers are widely used, yet many practical designs rely on highly integrated ICs that conceal their internal operation. The type of Li-ion charger outlined in this design is, somewhat surprisingly, not readily ...
