Active-clamp/reset PWM IC becomes more versatile - 26-Jun-03 Issue
of EDN The UCC3580 (www.ti.com], IC1 in Figure 1, is an
active-clamp/reset-PWM IC that has all the requisites of a power-supply IC
except for current limit. You can use the shutdown pin (16] for this purpose
(see the UCC3580 data sheet]. But when the shutdown pin activates, the
soft-start capacitor normally connected to Pin 15....[Design Idea by

Add on AM Modulator has High-Bandwidth - 09/11/98 EDN-Design
Ideas....The simple circuit in Figure 1 is an add-on modulator that
converts the output of a continuous-wave (CW] source to either an
amplitude-modulation (AM] or a suppressed-carrier-modulation (SCM]
format.....file has many circuits, scoll to find this one....[Design Idea by

AM Modulator - This circuit uses two signal generators to simulate an
Amplitude Modulated RF carrier wave. The output can be used to simulate the response
of LC and tank circuits….(electronic design added 6/07) |

AM Receiver - This is a compact three transistor, regenerative receiver with
fixed feedback. It is similar in principle to the ZN414 radio IC which is now replaced
by the MK484. The design is simple and sensitivity and selectivity of the receiver are
good…. [Design by Andy Collison] |
|
AM Transmitter - The circuit is in two halfs, an audio amplifier and an RF
oscillator. The oscillator is built around Q1 and associated components. The tank
circuit L1 and VC1 is tunable from about 500kHz to 1600KHz.… [Andy Collison] |

AM/FM/SW Active Antenna - This circuit shows an active antenna that can be
used for AM, FM, and shortwave SW. On shortwave band this active antenna is
comparable to a20 to30 foot wire antenna. This circuit uses receivers that use
untuned wire antennas, such as inexpensive units and car radios....(added 1/03)
