.. open-loop wireless transmitter based on the LTC6992 TimerBlox® silicon oscillator is used. For this design, the drive frequency is set at 216 kHz, which is below the LC tank resonant frequency of 266 kHz. The exact ratio of f LC_TX ...
.. circuit. Inside the integrator's feedback path, the gain of a second PGA (Gain B) multiplies the integrator's 3-dB frequency, thus providing bandwidth control. Figure 1. This ac-amplifier configuration offers both gain and ...
.. 301 kΩ. Capacitor C 3 connects to the comparator’s IN input. Along with R 1 and R 2 , C 3 sets the oscillation frequency according to the following simplified relationships: and where t PERIOD = t LOW + t HIGH . To maximize ...
.. or bad contact). It also features a counter, which is very handy when you want to count impulses, to estimate the value of frequency or to test an interface. (This part is shown as a sketch.) The probe in Figure 1 consists of two ...
.. at a rate of 10 µsec/K. User-selected scale factors range from 10 to 640 µsec/K. The complementary, fixed-frequency square-wave outputs of a power-transformer driver IC 1 , a Maxim MAX845 drive a Halo Electronics ...
.. 1 us to 33 sec. The delay time is controlled by the current sourced by the SET pin, which programs an internal oscillator frequency, while the bias voltage on the DIV pin selects a frequency divide ratio. The LT1783 op amp circuit ...
.. employs a controlled constant on-time, valley current mode architecture to provide fast load step response, high switching frequency and low duty cycle capability. The switching frequency range is 200 kHz to 2 MHz-its phase-locked loop ...
.. to low supply voltages. It could be used as the basis for a PWM control loop, a timer, or a VCO, or as a capacitance-to-frequency converter. It’s a nifty circuit for two reasons: It uses an open-drain comparator output to make ...
.. of the circuit is the classic half-bridge. The control circuit could be realised using an IC (so fixing the operating frequency), but there is a more economical solution which consists of a selfoscillating circuit where the two ...
