Abstract
A CMTI circuit includes a first detector that receives one or more output signals from an oscillator and a first enable signal and generates a first detection signal when the received output signals are determined to be substantially not oscillating at a first time. The CMTI circuit further includes a first activation signal generator that generates a first activation signal in response to the first detection signal to resume oscillation of the output signals.
Claims20
A common-mode transient immunity (CMTI) circuit, comprising:
- a first detector configured to receive at least one output signal from an oscillator and a first enable signal and generate a first detection signal when the at least one output signal is determined to be substantially not oscillating at a first time;
- and
- a first activation signal generator configured to generate a first activation signal in response to the first detection signal to resume oscillation of the at least one output signal.
A system, comprising:
- a transmitter configured to modulate a data input signal using an oscillator to generate at least one output signal, the transmitter including a first bleeder circuit configured to generate a first detection signal in response to a first enable signal when the at least one output signal is determined to be substantially not oscillating at a first time and generate a first activation signal in response to the first detection signal to resume oscillation of the at least one output signal;
- a galvanic isolator configured to transfer the at least one output signal from the transmitter;
- and
- a receiver configured to generate a data output signal in response to the transferred at least one output signal.
