Abstract: A current-mode direct conversion RF receiver is presented. In one set of embodiments the RF receiver comprises a simple transconductor input stage to create a current-mode modulated signal from a voltage-mode modulated signal. A downconversion mixer may be coupled to the transconductor input stage via a low impedance current cascode stage, and may operate to create a set of current-mode quadrature baseband signals from the current-mode modulated signal. The downconversion mixer may be implemented with a transistor-switching network, which may be driven by a phase locked loop (PLL) with quadrature outputs. The set of current-mode quadrature baseband signals may be converted back to the voltage domain by a transimpedance filter, which may perform channel selection for the receiver. The transimpedance filter may additionally include a low frequency zero to remove DC offsets.

Abstract: A low noise filter is arranged to receive an input signal from a downconverter. The low noise filter is constructed to block or cancel any DC offset in the input signal, as well as filter selected frequency components from the input signal. The low noise filter uses a shared capacitor both to handle the DC offset and to set filter response characteristics. As the low noise filter is implemented with a Frequency Dependent Negative Resistance (FDNR) device, the shared capacitor may be relatively small. The low noise filter has a load capacitor, with the output of the load capacitor coupled to a bias resistor and voltage. This bias structure cooperates with the load capacitor to set a high cutoff frequency for the low noise filter useful for blocking or canceling the DC offset.

Abstract: A method and apparatus are disclosed for providing pre-pay and post-pay calls. After receiving a pre-pay call, an integrated service platform obtains and transfers a pre-pay destination number and a pre-pay validation parameter to a switching system. The switching system then releases the pre-pay call extension to the integrated service platform and extends the pre-pay call using the pre-pay destination number. As the pre-pay call is in progress, the switching system monitors a duration of the pre-pay call and terminates the pre-pay call if the duration meets or exceeds a pre-pay amount indicated by the pre-pay validation parameter. In this manner, integrated service platforms, as required by prior approaches, are no longer required to be connected to the pre-pay call for the entire duration of the pre-pay call. Rather, an integrated service platform can request and receive authorization and call destination information, then be released for use by other calls.
