The present invention provides a cycle slip detector circuit for use with a phase and frequency detector circuit having first and second signal inputs, and arranged to provide first and second PLL control signal outputs responsive to clock edges in the first and second input signals respectively; ...
The peak detector circuit is non-linear; i.e., its output is not a linear function of the input, which can be disadvantageous in some applications. This circuit is suitable for detecting peak amplitudes of an audio signal, useful for normalising a signal, or for compression or limiting. ...
An impedance detector circuit (not shown) can be implemented using an op amp. The output of multiplexer ... Scott, Walter G. 被引量: 31发表: 2007年 VOICE SIGNAL PROCESSING CIRCUIT With regard to first voice intermediate frequency signals, signals having frequencies in the vicinity of their ...
If implemented in a product, a lock acquisition circuit is needed. This was not demonstrated. VTUNE needs to be “precharged” to steer the VCO frequency close enough to the reference so that lock can be captured. In Figure 19, the measured phase noise results were impressive using the HMC...

Many other chaotic systems, such as Chua’s circuit (multi-scroll) [46], can yield similar results. It should be noted that the performance of the communication receiver depends on the time it takes to self-synchronize. Lorenz, Burke–Shaw, and Chua systems self-synchronize relatively faster ...
The PA also utilized an adaptive bias circuit that further enhances its linearity and back-off efficiency across its frequency of operation. The proposed transformer utilized the combination of a distributed active transformer (DAT) and a figure-eight-shaped transformer [75,76]. The designed ...
David L. Terrell, in Op Amps (Second Edition), 1996 Principles of Frequency Compensation. So far in the text we have primarily focused on the frequency characteristics of the op amp with only occasional reference to the phase characteristics. Figure 10.7 shows a simple RC circuit and graphs sh...
