4-transistor H-bridge - an interesting 4-transistor H-bridge variant; this is
cheap and easy to build, and best of all is "smokeless" (i.e., no combination of
inputs can cause bridge to self-destruct). (added 7/06) |
|
6-transistor H-bridge - This is six transistor "Tilden style" H-bridge;
while not as old as original "basic H-bridge," this goes "way back," and is
basis for many BEAM driver circuits (added 7/06) |

Bridging enhances filter close in selectivity - 03/02/00 - EDN-Design Ideas:
General filters are bandpass filters that usually employ bridging couplings between
nonadjacent interstage couplings (Reference 1). This class of filters also includes
bridging coupling across filter input and output ports. The implementation of
input-to-output bridging already exists for a one-pole filter (Reference 2). For a
two-pole filter, dielectric resonators help achieve input-to-output bridging coupling

Circuit Adds Programmability to Sensor Amplifier - 03/21/02 - EDN-Design Ideas:
The pressure-sensor amplifier circuit of Figure 1 offers a number of advantages over
the traditional approach using the classic three-op-amp instrumentation amplifier. The
circuit can operate from a single supply and uses only two op amps and 1% resistors.
If the reference voltage, VREF, is 0V, the transducer gain for the circuit isTo ensure

Wattmeter - The extra input B is for a later SWR brigde project, also the TX
serial output will be in use later. The uncalibrated signal response is: +1/-1 dB from
1MHz to 450MHz. Input SWR vill varry from 1.00 to 1.30, depending on input frequency.
To make the SWR this good, you need to assemble the input circuit correct and adjust
the capasitor. Input power range: -60 to +30dBm that is 1 nW to 1 Watt. ….(circuit
